DESC:FIELD OF THE INVENTION

The present disclosure relates to switches and more particularly, relates to a switch assembly with at least one flat operating panel.

BACKGROUND

Commonly, electrical switches are employed for operating a wide range of appliances by controlling a flow of current to such appliances. In particular, the electrical switches are employed in electrical circuits to divert or interrupt the flow of current flowing towards the appliances, and thereby switching-ON or switching-OFF such appliances. Nowadays, the electrical switches are provided with a flat operating surface that can be operated to switch-ON or switch-OFF such electrical switches. Further, the electrical switches include a rocker that is pivotally movable by operating the flat operating surface. In such electrical switches, the rocker is oriented in an inclined direction with respect to the flat operating surface. Therefore, it is essential that the flat operating surface forms an optimal contact with the rocker when the flat operating surface is operated to actuate the rocker. Lack of such optimal contact may lead to uneven operation of the electrical switch which further results in an unsatisfactory user experience.

Therefore, there is a need for an improved switch assembly with a mechanism to provide a smooth operation of such a switch assembly.

However, it should be appreciated by a person skilled in the art that the present disclosure is equally applicable to other panel, i.e., the second panel 220-2, without departing from the scope of the present disclosure.

Figure 3a illustrates a perspective view of the first panel 220-1 of the switch assembly 100, according to an embodiment of the present disclosure. Figure 3b illustrates a sectional view of the first panel 220-1 taken along an axis A-A’ of Figure 3a, according to an embodiment of the present disclosure. Referring to Figure 3a and Figure 3b, the first panel 220-1 may include an upper surface 302 and a lower surface 304. The upper surface 302 may have a flat contour substantially parallel to the installation surface of the switch assembly 100.

In an embodiment, the first panel 220-1 may include, but is not limited to, at least one engaging portion 306 extending in a direction towards the rocker 204. In an embodiment, the at least one engaging portion 306 may include a first engaging portion 306-1 and a second engaging portion 306-2 spaced apart from the first engaging portion 306-1. The first engaging portion 306-1 and the second engaging portion 306-2 may collectively be referred to as the engaging portions 306, without departing from the scope of the present disclosure. Each of the engaging portions 306 may be adapted to pivotally move the rocker to push the movable contact element 214 via the pusher 208.

Further, the lower surface 304 may be provided with the engaging portions 306 adapted to pivotally move the rocker 204. Each of the first engaging portion 306-1 and the second engaging portion 306-2 may include an inclined surface 308 adapted to abut the first pair of legs 204-1 of the rocker 204 when the rocker 204 is pivotally moved in the first position.

Figure 4 illustrates a sectional view of the switch assembly 100, according to an embodiment of the present disclosure. Figure 5 illustrates a partial sectional view of a portion A of the switch assembly 100, according to an embodiment of the present disclosure. Referring to Figure 4 and Figure 5, the engaging portions 306 of the first panel 220-1 may be adapted abut the first pair of legs 204-1 of the rocker 204, when the rocker 204 is pivotally moved in the first position. In the first position of the rocker 204, the inclined surface 308 of the engaging portions 306 may be adapted to align in a parallel direction with respect to a surface 402 of the rocker 204. The engaging portions 306 of the first panel 220-1 may form a surface contact with the first pair of legs 204-1 when the rocker 204 is in the first position.

Similar to the first panel 220-1, the second panel 220-2 may include a plurality of engaging portions, similar to the engaging portions 306, provided on a lower surface of the second panel 220-2. The engaging portions of the second panel 220-2 may also be referred to as the engaging portions 306. The engaging portions 306 of the second panel 220-2 may include an inclined surface, similar to the inclined surface 308, adapted to abut the second pair of legs 204-2 of the rocker 204, when the rocker 204 is moved in the second position. The inclined surface of the engaging portions 306 of the second panel 220-2 may also be referred to as the inclined surface 308. In the second position the rocker 204, the inclined surface 308 of the engaging portions may be adapted to align in a parallel direction with respect to the surface 402 of the rocker 204. The engaging portions of the second panel 220-2 may form a surface contact with the second pair of legs 204-2, when the rocker 204 is in the second position.

Further, referring to Figures 3a and 3b, the lower surface 304 of the first panel 220-1 may include a supporting portion 310 adapted to be engaged with a spring 222 (as shown in Figure 2) to allow resilient movement of the first panel 220-1. Similarly, the lower surface of the second panel 220-2 may include a supporting portion adapted to be engaged with a spring 224 to allow resilient movement of the second panel 220-2. As mentioned earlier, each of the first panel 220-1 and the second panel 220-2 may be adapted to be resiliently pushed in the downward direction along the central axis C-C’ of the housing member 202. The spring may be, but is not limited to, a coil spring or a plate spring. The spring may be replaced with an elastic member having elasticity.

During an operation of the switch assembly 100, one of the first panel 220-1 and the second panel 220-2 may be pushed to pivotally move the rocker 204 between the first position and the second position. For instance, in the OFF-condition, the rocker 204 may be in contact with the engaging portions of the second panel 220-2. Such an arrangement may avoid collision between the second panel 220-2 and the rocker 204 during the operation of the switch assembly 100 and also provides the feeling of a smooth operation to a user. The second panel 220-2 may be pushed in the downward direction along the central axis C-C’ to pivotally move the rocker 204 by applying a force on an upper surface of the second panel 220-2.

Owing to such movement of the rocker 204, the pusher 208 may slide on the movable contact element 214 and simultaneously, push the movable contact element 214 to form an electrical contact between the movable contact element 214 and the first electrical terminal 216 with a riveted pillar. This results in the operation of the switch assembly 100 in the ON-condition. Upon releasing the force from the second panel 220-2, the spring 224 may push the second panel 220-2 in an upward direction, to its original position, along the central axis C-C’.

In the ON-condition, the rocker 204 may be in contact with the engaging portions 306 of the first panel 220-1. The first panel 220-1 may be pushed in the downward direction along the central axis C-C’ to pivotally move the rocker 204 by applying a force on the upper surface of the first panel 220-1. Owing to such movement of the rocker 204, the pusher 208 may slide on the movable contact element 214 and simultaneously, push the movable contact element 214 away from the first electrical terminal 216 with the riveted pillar. This results in the operation of the switch assembly 100 in the OFF-condition. Upon releasing the force from the first panel 220-1, the spring 222 may push the first panel 220-1 in an upward direction, to its original position, along the central axis C-C’.

As would be gathered, the present disclosure offers the switch assembly 100 having a flat operating panel, such as the first panel 220-1 and the second panel 220-2. As explained earlier, each of the first panel 220-1 and the second panel 220-2 may include the engaging portions 306 having the inclined surface 308 adapted to come in contact with the rocker 204. In the first position of the rocker 204, the inclined surface 308 of the engaging portions 306 of the first panel 220-1 may form a surface contact with the rocker 204. When the first panel 220-1 is pushed in the downward direction along the central axis C-C’, the engaging portion 306 may pivotally push the rocker 204 to the second position. In the second position of the rocker 204, the inclined surface 308 of the engaging portions of the second panel 220-2 may form a surface contact with the rocker 204.

Owing to a separated panel structure in which the first panel 220-1 and the second panel 220-2 are separated from each other, at least one of the inclined surface 308 of the first panel 220-1 and the second panel 220-2 may form a surface contact with the rocker 204 at the completion of the switching operation. Such surface contact may reduce spot impact and prevent wear and deformation between the second panel 220-2 and the rocker 204.

Owing to inclined surfaces 308 of the engaging portions 306, the optimal surface contact may be provided between the operating panels 220-1, 220-2, and the rocker 204. This results in the smooth operation of the switch assembly 100 and therefore, increases the overall user experience while operating the switch assembly 100. Further, this also results in a substantial reduction in force required to operate the switch assembly 100 and therefore, provides a light operation feeling to a user operating the switch assembly 100. Therefore, the switch assembly 100 of the present disclosure is operationally effective, flexible in implementation, cost-effective, compact, and convenient.

While specific language has been used to describe the present subject matter, any limitations arising on account thereto, are not intended. As would be apparent to a person in the art, various working modifications may be made to the method in order to implement the inventive concept as taught herein. The drawings and the foregoing description give examples of embodiments. Those skilled in the art will appreciate that one or more of the described elements may well be combined into a single functional element. Alternatively, certain elements may be split into multiple functional elements. Elements from one embodiment may be added to another embodiment. ,CLAIMS:We claim:
