To propose a switch capable of reducing power consumption at non-driving times, and applicable to a battery-driven portable electronic unit or the like for which consumption power is to be a problem.

The switch 1 is provided with a cylindrical stator 2, and a disc-like rotor 3 fitted on the stator 2 in free rotation. The stator 2 is provided with a disc-like vibrator 4, an insulating layer 6 formed on the vibrator 4, and lower electrodes 7a, 7b, 7c, 7d, 7e, 7f formed on the insulating layer 6. Further, on a side face of the stator 2, drawer conductors 8a, 8b, 8c, 8d, 8e, 8f are formed for electrically connecting the lower electrodes 7a, 7b, 7c, 7d, 7e, 7f with an outer wiring. Moreover, on a side face of the stator 2, driving terminals 5e, 5f, 5g, 5h are formed for impressing driving voltage on the vibrator 4.
