Claims

[Scope of utility model registration request]

A hollow case body is provided with an upwardly biased button part at the top, a signal output part is protruded from the bottom part, and a mounting part that is compatible with the contact switch. deployed,
A snap action lever whose central part is connected to the button part via a shaft part, one end is fixed to a fixing metal fitting, and the other end is provided with an impact hammer and always comes into contact with a stopper piece of a hollow case body. A small piezoelectric device comprising a piezoelectric transducer corresponding to the impact hammer, and a rectifier circuit connected to the piezoelectric transducer that rectifies the signal voltage generated in the piezoelectric transducer and outputs the signal to the signal output section. Switch.
