Claims

[Scope of utility model registration request]

(1) A metal plate with a piezoelectric element attached to a step provided at the open end of a bottomed cylindrical case to form a bimorph structure is placed so that the piezoelectric element is located inside the case;
Furthermore, the operating body is placed on this metal plate, and the operating body, which partially protrudes outside the metal plate and the receiving screw, is fixed inside the case by a receiving screw that fits into the threaded part provided on the outer periphery of the case. piezoelectric switch.

(2) The piezoelectric switch according to claim 1, which is a registered utility model, in which an elastic body such as rubber or a coil spring is inserted between the metal plate and the operating body.

(3) The piezoelectric switch as set forth in claim (1) of the utility model registration claim, wherein a stepped portion serving as a stopper for the operating body is provided inside the case.

(4) The piezoelectric switch according to paragraph (1) of the claim for utility model registration, which has a threaded portion on the outer periphery of the case so that it can be screwed onto a mounting board.
