A control switch is equipped with a detent mechanism that generates a click feeling in a dial knob as a result of a detent piece of a plunger member gets over detent crests of a detent crest member. A stopper is provided in the plunger member, and the position of vertical motion of the stopper is switched by means of a rectilinear actuator, thereby switching rotational operation of the dial knob between an enabled state and a disabled state.
