Abstract
A control knob device that may be used in a vehicle to control audio volume or the like includes a shaft connected with a knob cap, an elastic member pressed by the shaft to be elastically deformed, and a switch located adjacent to the elastic member. The switch includes a switch part configured to output a signal upon a deformation of the elastic member. A deformable member deformed by a load greater than that when the elastic member is deformed and the switch outputs the signal, is configured to change a relative position between the knob cap and the shaft.
