Claims

[Scope of utility model registration request]

A fixed contact is placed at the bottom of the dome-shaped inverted movable contact, and by pressing the movable contact through an elastic plate placed at the top of the movable contact, the movable contact is inverted and brought into contact with the fixed contact. In the push button switch configured as above, an intermediate plate is arranged above the movable contact and between the elastic plate, and a small protrusion is provided at the center of the lower surface of the intermediate plate for pressing the center of the movable contact. . A push button switch characterized in that the central portion of the movable contact can be suppressed by the small protrusion of the intermediate plate regardless of the direction of the pressing force of the elastic plate.
