Claims

[Scope of utility model registration request]

A switch case with a plurality of fixed contact pieces fixed to the bottom wall side, a conductive circular reversing spring disposed opposite to the fixed contact pieces, and a conductive circular reversing spring installed inside the switch case so that the reversing spring can be moved up and down. a return coil spring that is elastically supported by the switch case, a push button that is fitted into a fitting hole formed in the upper wall of the switch case and has a pressing part for pressing the reversal spring on the lower surface; is formed integrally with the outer periphery, and the outer periphery end is installed on the switch case side,
A push button switch comprising a dome-shaped elastic support that elastically deforms in a buckling shape when the reversing spring comes into contact with a predetermined fixed contact piece when the push button is pressed.
