DESC:FIELD OF THE INVENTION

The present disclosure relates to switch assemblies and more particularly relates to a switch assembly adapted to operate in a plurality of directions, have a symbol illumination, and haptic response to enhance driver’s experience.

BACKGROUND

Automobiles/vehicles are provided with headlights, indicators, wipers, and the like to operate as per the requirement of a driver. While driving, the driver may operate the vehicle in various modes, for example, a track mode, an eco-mode, a cruise mode, a navigation mode, etc. In such a scenario, conventionally, a switch assembly is operated in a plurality of directions to perform the various modes and/or to operate the headlights, the indicators, and the wipers. The switch assembly is configured with push buttons, rotatable knobs, push knobs, and the like to execute the desired operations to perform the various modes in the vehicle.

The switch assembly may be mounted on a stock of a steering wheel of the vehicle. Furthermore, the switch assembly includes a lever mounted on a knob. Moreover, the lever is coupled to a ball and a spring arranged within the knob. The ball and the spring enable movement of the knob limited to three directions and return the knob to the idle position. However, the conventional configuration of the switch assembly has limitations, that, the switch assembly requires an increased number of components. This leads to a complex design, installation, and operation of the switch assembly. Furthermore, the complexity in the configuration reduces driver’s experience and therefore decreases the driving capability of the driver, and thus becomes inefficient in handling and use. Further, the conventional configuration of the switch assembly does not have any illumination of light, which reduces the comfort of the driver while accessing the switch assembly. Moreover, making an efficient configuration of the switch assembly warrants change in the entire switch assembly which increases the overall cost of the switch assembly.

Therefore, in light of the foregoing discussions, there is a need to provide a switch assembly that may operate in a plurality of directions while overcoming the limitations/drawbacks of the conventional switch assembly.

Further, the illuminated light is projected on the transparent part of the push knob 102, the retainer knob 104, and the body 106 (as shown in Figure 1). Specifically, the illuminated light reaches the transparent structure 302 of the retainer knob 104 and reflects at an inner surface of the retainer knob 104 on contacting a white-coated surface. These transparent parts or structures may be manufactured using glass material, transparent fiber, and the like. The plurality of LEDs 704 (as shown in Figure 7B) illuminates the transparent part of the push knob 102, the retainer knob 104, and the body 106 to indicate a response against the pressure on the push knob 102, the retainer knob 104, and the body 106. Further, the shaded portions 802 are illuminated at laser etched area as per predetermined shape and size. The laser etched area is formed by applying white paint as a first layer applied on the transparent structure 302 of the retainer knob 104. Further, black paint is applied as a second layer on the white-coated part of the transparent structure 302. Furthermore, the symbol laser is etched on a top surface by removing the coating of the black paint on the transparent structure 302.
