する圧電式スイツチ。 A case having a plurality of terminals implanted therein, a plunger movably mounted inside the case, a piezoelectric plate polarized in the thickness direction, having electrodes on both sides, and mounted inside the case via an elastic member; A piezoelectric device comprising a conductive plate fixed to the top surface of the piezoelectric plate and a dome-shaped spring placed on the conductive plate, and when a plunger is pushed down, the dome-shaped spring is reversed and strikes the conductive plate. In a type switch, a plunger is formed by integrally molding a cylindrical pressing part, a thin disc part connected to the lower end of the pressing part, and a protruding part protruding downward from the center of the disc part from an elastic material. What is claimed is: 1. A piezoelectric switch, characterized in that the protruding portion is brought into contact with a dome-shaped spring, and the entire plunger is housed inside a case when the plunger is pushed down.
