Figure 1, illustrates an exploded view of the three-position switch (100) for vehicles in accordance with an embodiment of the invention. Further, Figure 2, Figure 3, Figure 4, and Figure 5 illustrates a front view, a top view, a first side view and a second side view respectively of the three-position switch.

The three-position switch (100) comprising a knob assembly (102, 104) including a push knob (102) and a slider knob (104). The slider knob (104) being adapted to receive the push knob (102) and being adapted to exhibit movement in a first direction (D1) and a second direction (D2) opposite to the first direction (D1). The push knob (102) being adapted to exhibit movement in a third direction (D3) being perpendicular to the first direction (D1) and the second direction (D2).

The three-position switch (100) comprising a casing (106, 108) adapted to receive the knob assembly (102, 104). The casing (106, 108) is adapted to accommodate the knob assembly and ensure proper alignment and movement of the knobs (102, 104) within the switch (100).

The three-position switch (100) comprising a first detector switch (110a) disposed along the first direction within the casing (106, 108) such that in operation the first detector switch (110a) gets actuated by movement of the slider knob (104) in the first direction, a second detector switch (110b) disposed along the second direction within the casing (106, 108) such that in operation the second detector switch (110b) gets actuated by movement of the slider knob (104) in the second direction and a tact switch (110c) disposed within the casing (106, 108) such that in operation the tact switch (110c) gets actuated by movement of the push knob (104) in the third direction.

In an embodiment of the invention, the slider knob (104) together with the push knob (102) are adapted to exhibit movement in the first direction and the second direction, the push knob (102) being adapted to exhibit movement independent of the slider knob (104) in the third direction.

Unlike the slider knob (104), which primarily moves horizontally along the first and second directions, the push knob (102) can be pressed or pushed vertically, perpendicular to the sliding directions. This unique movement in the third direction (D3) is designed to provide an additional control function or feature within the three-position switch (100).

In an embodiment of the invention, the push knob (102) comprises a proximal portion (102a), a distal portion (102c) and an intermediate portion (102b), the proximal portion (102a) being adapted to receive the actuating force along the third direction; the intermediate portion (102b) being operably connected to a carrier element (112), the carrier element (112) being adapted to transfer an actuating force received in the first direction to the first detector switch (110a) and transfer an actuating force received in the second direction to the second detector switch (110b); the distal portion (102c) being adapted to directly transfer the actuating force received along the third direction to the tact switch (110c).

In an embodiment of the invention, a spring (116) is disposed around the intermediate portion (102b) of the push knob (102) to provide resilient force to the push knob (102) to return to its original position as the instance of removal of actuating force from the push knob (102).

In an embodiment of the invention, a flapper (118) is provided to prevent the ingress of the dust, water and other contaminants. In an embodiment of the invention, a circlip (120) is provided to hold and secure the push knob (102) in the three-position switch (100).

In an embodiment of the invention, the distal portion (102c) of the push knob (102) comprises a tapered projection. In an embodiment of the invention, the distal portion (102c) of the push knob (102) is extended in Z plane.

In an embodiment of the invention, the carrier element (112) comprises a first part (112b) with a second part (112c). In an embodiment of the invention, the second part (112c) being a projection on the first part (11b). In an embodiment of the invention, the first part (112b) of the carrier element (112) and the second part (112c) of the carrier element form a T shape like structure.

Referring to Figure 6, 7 and 8, illustrates a front sectional view of the three-position switch after removing of knob assembly, housing and carrier respectively. In an embodiment of the invention, the carrier element (112) comprises an aperture (112a) for allowing the intermediate portion (102b) of the push knob (102) to traverse there-through, the intermediate portion (102b) of the push knob (102) interacts with the aperture of the carrier element (112) during movement of the push knob (102) along the third direction to provide an push-cancellation action. This push-cancellation mechanism ensures that when the push knob is moved along the third direction, the force is directed solely to the tact switch, preventing unintended actuation of the detector switches (110a and 110b).

In an embodiment of the invention, the first part (112b) of the carrier element (112) comprises the aperture (112a) for allowing the intermediate portion (102b) of the push knob (102) to traverse there-through.

In an embodiment of the invention, the casing (106, 108) comprises a housing (106) and a cap element (108). In an embodiment of the invention, the housing (106) and cap element (108) may be snap fitted or pasted or welded or joint by any other conventional mechanism. The housing (106) comprises a first slot (106a) adapted to receive the first detector switch (110a) and a second slot (106b) adapted to receive the second detected switch (110b), the cap element (108) comprising a third slot (108a) adapted to receive the tact switch (110c). The first slot (106a) is precisely tailored to fit the dimensions of the first detector switch (110a), ensuring a snug and stable fit. Likewise, the second slot (106b) is adapted to accommodate the second detector switch (110b), providing a secure location for its placement within the housing (106). This arrangement helps to prevent unintended movement or dislodging of the detector switches during operation.

In an embodiment of the invention, the first slot (106a) is provided at a first height (H1) of the housing (106). This height (H1) is chosen to ensure proper placement and alignment to securely place the first detector switch (110a) at the appropriate position within the three-position switch (100) for optimal functionality. In an embodiment of the invention, the second slot (106b) is provided at a second height (H2) of the housing (106). This height (H2) is chosen to ensure proper placement and alignment to securely place the second detector switch (110b) at the appropriate position within the three-position switch (100) for optimal functionality. In an embodiment of the invention, the first height (H1) being different from the second height (H2). This difference in height allows for proper alignment and functioning of the corresponding detector switches (110a, 110b) within the three-position switch (100).

In an embodiment of the invention, the housing (106) is in Z shape like structure with two slots at extreme end of Z shape.

In one embodiment of the invention, the first slot (106a) and the second slot (106b) are disposed opposite each other, but not aligned in the same plane. The first slot (106a) and the second slot (106b) are disposed in a first X plane (X1) and a second X plane (X2) respectively, which are parallel to each other and is separated by a distance (A) in plane Y, which is perpendicular to the first plane and second plane. This arrangement mutatis mutandis applies to the first detector switch (110a) and the second detector switches (110b).

By employing this configuration, a compact switch design can be achieved. For example, if the detector switches (110a, 110b) were aligned in the same plane facing each other, the casing's total width would include the combined width of the first detector switch (110a), the width of the second detector switch (110b), the width of the carrier element (112), as well as the tolerance between the detector switches (110a, 110b) and the carrier element (112), and between the detector switches (110a, 110b) and the casing (106, 108). However, by arranging them out of plane and making them interact with different part of the carrier element (112), the overall width of the casing (106, 108) can be decreased.

In present configuration, the first detector switch (110a) interacts with the first part (112b) of the carrier element (112) and the second detector switch (110b) interacts with the second part (112c) of the carrier element (112), which is a projection substantially projecting from the middle of the first part (112b) of the carrier element (112). This way, the total width would be lesser than the combined width of the first detector switch (110a), the width of the second detector switch (110b), the width of the carrier element, as well as the tolerance between the detector switches (110a, 110b) and the carrier element (112), and between the detector switches (110a, 110b) and the casing (as calculated in above example).

This configuration allows for a more compact switch design, reducing the space required for installation while maintaining the functionality of the detector switches (110a, 110b). The specific dimensions, shapes, and materials used may vary based on the implementation and application of the invention.

In an embodiment of the invention, the third slot (108a) is provided at about a centre location of the cap element (108) corresponding to a neutral position of the push knob (102). In this embodiment of the invention, the third slot is provided in a z plane of the switch.

FIGURE 9(A) illustrates a three-position switch (100) in a non-actuated state which corresponds to both electrical circuits in non-conducting state in accordance with an embodiment of the invention. In the non-actuated state, the three-position switch (100) is in its default position, and both the push knob (102) and the slider knob (104) remain stationary. There is no active movement of the knob assembly (102, 104) or pressing of either detector switch (110a, 110b). This state serves as the initial or neutral position of the three-position switch (100), awaiting user input.

FIGURE 9(B) illustrates a three-position switch (100) in a first actuated state which corresponds to a first electrical circuit being in conducting state in accordance with an embodiment of the invention. In the first actuated state, the knob assembly (102, 104) is engaged and moved in the first direction (D1). As the knob assembly (102, 104) is moved in the first direction (D1) by the user, the knob assembly (102, 104) being operably connected to a carrier element (112), transfer the actuating force to the carrier element (112) to move the carrier element (112) in a first direction (D1) to thereby actuate the first detector switch (110a). In an embodiment of the invention, the first part (112b) of the carrier element (112) interacts with the first detector switch (110a). Upon removal of actuating force by the user, the knob assembly (102, 104) and the carrier (112) both return to a default position. (as shown in Figure 9(A)).

In one embodiment of the invention, the knob assembly (102, 104) may be provided with a lateral spring (not shown) to bring back the knob assembly (102, 104) from the first actuated state to its non-actuated state or default position, upon removal of the actuating force by the user.

In one embodiment of the invention, the carrier element (112) may be provided with a spring-ball mechanism or mountain-valley parking mechanism or any other mechanism to bring back the carrier element (112) from the first actuated state to its non-actuated state or default position, upon removal of the actuating force by the user.

In an embodiment of the invention, after the removal of force, the three-position switch (100) may remain engaged for a small duration, then user by pushing the push knob (102) in the third direction enables the push knob (102) to traverses through the aperture (112a) of the carrier element (112) thereby enabling the distal portion of the push knob (102) to interact with the tact switch (110c) to provide a cancellation of the first actuated state, thereby bringing the three-position switch (100) in a third actuated state which corresponds to the third electrical circuit being in conducting state (as shown in Figure 9(D)).

In one embodiment, user may anytime after the three-position switch (100) in a first actuated state, user by pushing the push knob (102) in the third direction enables the push knob (102) to traverses through the aperture (112a) of the carrier element (112) thereby enabling the distal portion of the push knob (102) to interact with the tact switch (110c) to provide a cancellation of the first actuated state to thereby bringing the three-position switch (100) in a third actuated state which corresponds to the third electrical circuit being in conducting state (as shown in Figure 9(D)).

FIGURE 9 (C) illustrates a three-position switch in a second actuated state which corresponds to a second electrical circuit being in conducting state in accordance with an embodiment of the invention. In the second actuated state, the knob assembly (102, 104) is engaged and moved in the second direction (D2). As the knob assembly (102, 104) is moved in the second direction (D2) by the user, the knob assembly (102, 104) being operably connected to a carrier element (112), transfer the actuating force to the carrier element (112) to move the carrier element (112) in a second direction (D2) to thereby actuate the second detector switch (110b). In an embodiment of the invention, the second part (112c) of the carrier element (112) interacts with the second detector switch (110b). Upon removal of actuating force by the user, the knob assembly (102, 104) and the carrier element (112) return to a default position or non-actuated state. (as shown in Figure 9(A)).

In one embodiment of the invention, the knob assembly (102, 104) may be provided with a lateral spring to bring back the knob assembly (102, 104) from the second actuated state to its non-actuated state or default position, upon removal of the actuating force by the user.

In one embodiment of the invention, the carrier element (112) may be provided with a spring-ball mechanism or mountain-valley parking mechanism or any other mechanism to bring back the carrier (112) from the second actuated state to its non-actuated state or default position, upon removal of the actuating force by the user.

After the removal of force, the switch (100) may remain engaged for a small duration, then user by pushing the push knob (102) in the third direction enables the push knob (102) to traverses through the aperture (112a) of the carrier element (112) thereby enabling the distal portion of the push knob (102) to interact with the tact switch (110c) to provide a cancellation of the second actuated state to thereby bringing the three-position switch in a third actuated state which corresponds to the third electrical circuit being in conducting state (as shown in Figure 9(D)).

In one embodiment, user may anytime after the three-position switch in a second actuated state, user by pushing the push knob (102) in the third direction enables the push knob (102) to traverses through the aperture (112a) of the carrier element (112) thereby enabling the distal portion of the push knob (102) to interact with the tact switch (110c) to provide a cancellation of the second actuated state to thereby bringing the three-position switch in a third actuated state which corresponds to the third electrical circuit being in conducting state (as shown in Figure 9(D)).

FIGURE 10(A) illustrates a three-position switch in a non-actuated state which corresponds to both electrical circuits in non-conducting state in accordance with an embodiment of the invention. In the non-actuated state, the three-position switch (100) is in its default position, and both the push knob (102) and the slider knob (104) remain stationary. There is no active movement of the knob assembly (102, 104) or pressing of either detector switch (110a, 110b). This state serves as the initial or neutral position of the three-position switch (100), awaiting user input.

FIGURE 10(B) illustrates a three-position switch in a first actuated state which corresponds to a first electrical circuit being in conducting state in accordance with an embodiment of the invention. In the first actuated state, the knob assembly (102, 104) is engaged and moved in the first direction (D1). As the knob assembly (102, 104) is moved in the first direction (D1) by the user, the knob assembly (102, 104) being operably connected to a carrier element (112), transfer the actuating force to the carrier element (112) to move the carrier element (112) in a first direction (D1) to thereby actuate the first detector switch (110a). In an embodiment of the invention, the first part (112b) of the carrier element (112) interacts with the first detector switch (110a). Upon removal of actuating force by the user, the knob assembly (102, 104) returns to a default position but the carrier element (112) remains parked at the first actuated position to keep the first detector switch (110a) in the first actuated state.(as shown in Figure 10(D))

In one embodiment of the invention, the knob assembly (102, 104) may be provided with a lateral spring (not shown) to bring back the knob assembly (102, 104) from the first actuated state to its non-actuated state or default position, upon removal of the actuating force by the user.

Now to bring the three-position switch from a first actuated state to a non-actuated state or rather to bring the carrier element (112) from being parked to back to its default position, the user by pushing the push knob (102) in the third direction enables the push knob (102) to traverses through the aperture (112a) of the carrier element (112) to bring back the carrier element(112) to the default position and thereby enabling the distal portion of the push knob (102) to interact with the tact switch (110c) to provide a cancellation of the first actuated state to thereby bringing the three-position switch in the default position. (as shown in Figure 10(A)).

In an embodiment of the invention, the user by pushing the push knob (102) with a first level of force, bring back the carrier element (112) to the default position only, thereby bring the three-position switch from a first actuated state to a default position or a non-actuated state (as shown in Figure 10(A)). In an embodiment of the invention, the user by pushing the push knob (102) with a second level of force, the second level of force being greater than the first level of force, enables the distal portion of the push knob (102) to interact with the tact switch (110c) to provide a cancellation of the first actuated state thereby bringing the three-position switch in a third actuated state which corresponds to the third electrical circuit being in conducting state (as shown in Figure 10(E)).

In an embodiment of the invention, a user can directly apply a second level of force, which brings both carrier element (112) to the default position and enables the distal portion of the push knob (102) to interact with the tact switch (110c) to provide a cancellation of the first actuated state thereby bringing the three-position switch in a third actuated state which corresponds to the third electrical circuit being in conducting state (as shown in Figure 10(E)).

In an embodiment of the invention, the second level of force brings the distal portion (102c) of push knob (102) in a threshold range, which is suitable to interact with the tact switch (110c)to provide a cancellation of the first actuated state thereby bringing the three-position switch in a third actuated state which corresponds to the third electrical circuit being in conducting state (as shown in Figure 10(E)).

FIGURE 10(C) illustrates a three-position switch in a second actuated state which corresponds to a second electrical circuit being in conducting state in accordance with an embodiment of the invention. In the second actuated state, the knob assembly (102, 104) is engaged and moved in the second direction (D2). As the knob assembly (102, 104) is moved in the second direction (D2) by the user, the knob assembly (102, 104) being operably connected to a carrier element (112), transfer the actuating force to the carrier element (112) to move the carrier element (112) in a second direction (D2) to thereby actuate the second detector switch (110b). In an embodiment of the invention, the second part (112c) of the carrier element (112) interacts with the second detector switch (110b). Upon removal of actuating force by the user, the knob assembly (102, 104) returns to a default position but the carrier element (112) remains parked at the second actuated position to keep the second detector switch (110b) in the second actuated state. (not illustrated)

In one embodiment of the invention, the knob assembly (102, 104) may be provided with a lateral spring to bring back the knob assembly (102, 104) from the second actuated state to its non-actuated state or default position, upon removal of the actuating force by the user.

Now to bring the three-position switch from a second actuated state to a non-actuated state or rather to bring the carrier element (112) from being parked to back to its default position, the user by pushing the push knob (102) in the third direction enables the push knob (102) to traverses through the aperture (112a) of the carrier element (112) to bring back the carrier element(112) to the default position and thereby enabling the distal portion of the push knob (102) to interact with the tact switch (110c) to provide a cancellation of the second actuated state to thereby bringing the three-position switch in the default position. (as shown in Figure 10(A)).

In an embodiment of the invention, the user by pushing the push knob (102) with a first level of force, bring back the carrier element (112) to the default position only, thereby bring the three-position switch from a second actuated state to a default position or a non-actuated state (as shown in Figure 10(A)). In an embodiment of the invention, the user by pushing the push knob (102) with a second level of force, the second level of force being greater than the first level of force, enables the distal portion of the push knob (102) to interact with the tact switch (110c) to provide a cancellation of the second actuated state thereby bringing the three-position switch in a third actuated state which corresponds to the third electrical circuit being in conducting state (as shown in Figure 10(E)).

In an embodiment of the invention, a user can directly apply a second level of force, which brings both carrier element (112) to the default position and actuates the tact switch (110c) to provide a cancellation of the second actuated state thereby bringing the three-position switch in a third actuated state which corresponds to the third electrical circuit being in conducting state (as shown in Figure 10(E)).

In an embodiment of the invention, the second level of force brings the distal portion (102c) of push knob (102) in a threshold range, which is suitable for the actuation of the tact switch (110c) to provide a cancellation of the second actuated state thereby bringing the three-position switch in a third actuated state which corresponds to the third electrical circuit being in conducting state (as shown in Figure 10(E)).

FIGURE 11 illustrates an interaction of the distal portion (102c) of the push knob (102) with the tact switch (110c).

In an embodiment of the invention, the three-position switch being a turn signal switch or direction switch, wherein the first actuated state (first electrical circuit) and the second actuated state (second electrical circuit) corresponds to left winker and right winker. In an embodiment of the invention, the third actuated state corresponds to push cancellation of left winker and right winker and simultaneously to operate hazard or SOS.

In one embodiment of the invention, the slider knob (104) is coupled with a spring to bring back the slider knob (104) from the first actuated state or the second actuated state to its non-actuated state or default position.

In an embodiment of the invention, a ball-spring mechanism (114) is disposed between the housing (106) and the carrier element (112). The ball-spring mechanism (114) consists of a ball and a spring element.

This ball-spring mechanism (114) serves a specific function within the three-position switch (100) and contributes to its overall operation. The ball-spring mechanism (114) enhances the overall functionality and reliability of the three-position switch (100). It ensures consistent and accurate actuation of the switches (110a, 110b, 110c), providing a tactile and responsive user experience. By offering controlled movement and guidance, the ball- spring mechanism (114) contributes to the smooth operation and longevity of the three-position switch (100).

The placement of the ball-spring mechanism (114) between the housing (106) and the carrier element (112) allows for controlled movement and engagement. The ball-spring mechanism (114) facilitates smooth and precise movement of the carrier element (112) within the housing (106), ensuring proper alignment and actuation of the switches (110a, 110b, 110c).

When the carrier element (112) moves in response to the user’s input, the ball-spring mechanism
(114) provides resistance and guidance. The spring element exerts a force on the ball, creating tension. As the carrier element (112) moves, the ball rolls or slides along a track or groove within the housing (106), guided by the tension of the spring. The track or groove comprises a mountain-valley structure. This mechanism helps maintain alignment and stability during the movement of the carrier element (112). This mechanism helps in parking of the carrier element (112) and in returning back of the carrier element (112) to the default position.

In an embodiment of the invention, the aperture (112a) of the carrier has a first and a second tapered ramp like wall facing each other.

In an embodiment of the invention, the tact switch (110c) is disposed on a Printed circuit board (PCB) (122). In an embodiment of the invention, the tact switch (110c) is provided with a protective means (124) such as grommet or like.

Further, Figure 12, Figure 13 and Figure 14 illustrates a front view, a side view and a top view respectively of the three-position switch in accordance with another embodiment of the invention. In this embodiment, the tact switch (110c) is disposed in the housing (106). In an embodiment of the invention, the tact switch (110c) is disposed in third slot (106c) and is disposed in Y plane of the switch.

Referring to Figure 15 and 16, illustrates a front sectional view of the three-position switch after removing of knob assembly and housing respectively. The actuation of first detector switch (110a) i.e. first actuated state and the second detector switch (110b) i.e. the second actuated state and returning to non-actuated state is same as explained via Figure 9. The mechanism for actuation of tact switch (110c) in third slot (106c) for push cancellation requires a specific construction of the distal portion (102c) of the push knob (102).

Referring to Figure 17 and 18, illustrates an interaction of the distal portion (102c) of the push knob with the carrier element (112) and tact switch (110c) respectively. In an embodiment of the invention, the distal portion (102c) of the push knob (102) comprises a projection extended in Y plane to actuate the tact switch (110c) disposed below the distal portion (102c) in Y plane. In an embodiment of the invention, the projection being a tapered shaped projection. In an embodiment of the invention, the aperture (112a) in the carrier element (112) is constructed to accommodate the distal portion (102c) of the push knob (102).

This construction is advantageous when there exists space constraint in the handle console of the two wheeler vehicle.
