Figure 1 illustrates an exploded view of a 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) and ensure proper alignment and movement of the knobs (102,104) within the switch (100). The casing (106, 108) accommodating a first detector switch (110a) along the first direction such that in operation the first detector switch (110a) gets actuated by movement of the slider knob (104) in the first direction (D1), the casing (106, 108) accommodating a second detector switch (110b) along the second direction such that in operation the second detector switch (110b) gets actuated by movement of the slider knob (104) in the second direction, and the casing (106, 108) accommodating a third detector switch (110c) along the third direction such that in operation the third detector switch (110c) gets actuated by movement of the push knob (102) 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 third detector switch (110c).

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.

According to an embodiment of the present invention, the first direction resembles with a direction along negative x-axis, the second direction resembles with a direction along positive x axis, the third direction resembles with a direction along negative z- axis in accordance with cartesian co-ordinate system.

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 at 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 carrier element (112) comprises a first part (112b) and a second part (112c). In an embodiment of the invention, the second part (112c) extends from the first part (111b) so as to form a T shape like structure.

Figure 6, 7 and 8, illustrates a front sectional view of the three-position switch after removing of the knob assembly, the housing and the carrier element 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 a push-cancellation action.

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), 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 third detector 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, in the same plane but separated by a distance. 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 the 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 so as to face 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, 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, all measured along the X-axis. However, by arranging them out of plane and making them interact with different portion of the carrier element’s (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 along the X- axis 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.

Referring to Fig. 9(A) to 9(F), the operation of the three-position switch is explained.

FIGURE 9(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 or default position of the three-position switch (100), awaiting user input.

FIGURE 9(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), transfers the actuating force to the carrier element (112) to move the carrier element (112) in the first direction (D1) to make contact with the first detector switch (110a), thereby actuating the first detector switch (110a). In an embodiment of the invention, the first part (112a) of the carrier element (112) makes contact with the first detector switch (110a).

Upon removal of actuating force by the user, the knob assembly (102, 104) and the carrier element (112) returns to a neutral position (as shown in Figure 9(C)) but the three position switch remains in a first actuated state for a short duration. The user, then, by pushing the push knob (102) in a third direction, provides the cancellation of the first actuated state, and thereby bringing the third position switch in a third actuated state by actuating the third detector switch (110c).(as shown in Figure 9 (F))

In an embodiment of the invention, upon removal of actuating force by the user, the knob assembly (102, 104) returns to the neutral position but the carrier element (112) remain parked in the first direction or in contact making position with the first detector switch (110a).The user, then, by pushing the push knob (102) in a third direction, brings the carrier element (112) to return back to the neutral position or default position. Simultaneously, the distal portion (102c) of the push knob (102) comes in contact with the third detector switch (110c) to bring the third detector switch (110c) in an actuated state.

In an embodiment of the invention, a first level of force may be applied to bring the carrier element (112) in the default position or neutral position and a second level of force may be applied to actuate the third detector switch (110c) to bring the three position switch in a third actuated state. The second level of force is greater than the first level of force.

FIGURE 9(D) 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), transfers the actuating force to the carrier element (112) to move the carrier element (112) in the second direction (D2) to make contact with the second detector switch (110b), thereby actuating the second detector switch (110b).

In an embodiment of the invention, the second part (112b) of the carrier element (112) makes contact with the second detector switch (110b).

Upon removal of actuating force by the user, the knob assembly (102, 104) and the carrier element (112) returns to a neutral position (as shown in Figure 9(E)) but the three position switch remains in a second actuated state for a short duration. The user, then, by pushing the push knob (102) in a third direction, provides the cancellation of the second actuated state, and thereby bringing the third position switch in a third actuated state by actuating the third detector switch (110c).(as shown in Figure 9 (F))

In an embodiment of the invention, upon removal of actuating force by the user, the knob assembly (102, 104) returns to the neutral position but the carrier element (112) remain parked in the second direction or in contact making position with the second detector switch (110b). The user, then, by pushing the push knob (102) in a third direction, brings the carrier element (112) to return back to the neutral position or default position. Simultaneously, the distal portion (102c) of the push knob (102) comes in contact with the third detector switch (110c) to bring the third detector switch (110c) in an actuated state.

In an embodiment of the invention, a first level of force may be applied to bring the carrier element (112) in the default position or neutral position and a second level of force may be applied to actuate the third detector switch (110c) to bring the three position switch in a third actuated state. The second level of force is greater than the first level of force.

Figure 10illustrates an interaction of the distal portion (102c) of the push knob (102) with the third detector 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 corresponds to a hazard or SOS switch of the vehicle.

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), and increases sensitivity for providing a 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 third detector switch (110c) is disposed on a Printed circuit board (PCB) (122). In an embodiment of the invention, the third detector switch (110c) is provided with a protective means such as grommet or like.
