ABSTRACT:
A push-on switch according to the present invention is constructed so that a pressing part faces the top surface of a dome-shaped movable contact, across a given clearance. Such a construction allows the pressing part to be pressed a distance until the pressing part touches the movable contact to be utilized for pre-loading, even if the movable contact has a short operation stroke.
