Claims

[Scope of utility model registration request]

a stem arranged to be pressable against the case; a pressing spring actuated by movement of the stem;
and a switch element disposed in the case, and by pressing the stem, the working protrusion of the pressing spring presses the movable contact pressing part at the tip of the pressing piece of the switch element, and the movable contact of the switch element is pressed. A push button switch which returns to its original unpressed state by turning on a child and a fixed contact and removing a pressing force, characterized in that an elliptical working protrusion is formed on the pressing spring.
