Claims

[Claims for Utility Model Registration] A conductive coil spring is interposed between fixed contact pieces provided on the body to face each other, and as the actuator is displaced between the push-in position and the return position. In the push switch in which one end of the coil spring is switched between an open state and a closed state with respect to one fixed contact piece, the winding near the one end of the coil spring moves away from the axis as it approaches its tip. It is formed in a spiral shape that approaches the center, and when the actuator is set at the return position, the entire winding near the one end is flattened and comes into contact with the one fixed contact. A push switch characterized in that the push switch is located at a distance from the fixed contact piece or is separated from the one fixed contact piece.
