DESC:FIELD OF THE INVENTION

The present disclosure relates to automotive vehicles. Particularly the present disclosure related to consumer electronics and automotive vehicles and, more particularly, relates to a switch assembly for a vehicle.

BACKGROUND

The information in this section merely provides background information related to the present disclosure.

Automobiles usually include a switch assembly for performing multiple operations while riding a vehicle. Generally, the switch assembly of the vehicle is configured on a handlebar, a panel, a steering handle, or another suitable place to operate easily by the end users. The user may use the switch assembly to operate from a left-hand side direction and a right-hand side direction of the handlebar for performing a switch-functioning operation. To perform the switch-functioning operation such as a turn signal lamp, headlight, starting, locking, navigation, switching to an open seat, etc., we may require one or more switches.

Currently, the available traditional mechanized switch for the vehicle has a greater number of components and the design is also complicated to operate for the user. The traditional mechanized switch cannot meet the requirements of an electric vehicle. Owing to the aforesaid design, the switch of the vehicle lacks comfort for the users while riding the vehicle.

Therefore, it is desirable to provide an improved switch assembly that can overcome at least above-mentioned shortcomings of the existing switch assemblies.

The drawbacks/difficulties/disadvantages/limitations of the conventional techniques explained in the background section are just for exemplary purposes and the disclosure would never limit its scope only such limitations. A person skilled in the art would understand that this disclosure and below mentioned description may also solve other problems or overcome the other drawbacks/disadvantages of the conventional arts which are not explicitly captured above.
