Description

Rotary switch unit for vehicle {VEHICULAR ROTARY SWITCH UNIT}

The present invention relates to a rotary switch unit for a vehicle, and more particularly, to a rotary switch unit for a vehicle capable of generating a switching signal according to a rotation operation.

Switches are widely used as parts for selection and operation in a wide variety of devices such as vehicles, machine tools, terminals, multimedia devices, and game machines.

A wide variety of switches have been developed and used according to the types of devices to be applied, and continuous research and development is being made to enable various functional selections of devices. Representative switches include a push switch that can be operated by simple push operation, a rotary switch that can be operated in an axial direction, and a lever-type switch.

For example, a multi-function switch is installed in a vehicle produced recently. The multi-function switch may be used to control operations of lights and fog lamps, wipers, various audio devices, vehicle windows, and the like. The multi-function switch increases the operability of various devices, so that the driver does not lose frontal attention even when operating various devices while driving. This multi-function switch adopts a rotary knob or a knob capable of complex movements.
