Abstract: The push switch of the invention includes: a case including a plurality of contact terminals placed on an inner bottom surface thereof and a contact member that includes a plurality of conductive protruding portions which come into contact with the plurality of contact terminals at selected positions while sliding on the inner bottom surface of the case; a fulcrum portion supported in a rotatable state by an axis parallel to the inner bottom surface of the case; and an elastic bent portion for connecting the protruding portions with the fulcrum portion. The push switch further includes a sliding body which is supported so as to move up and down along a direction vertical to the inner bottom surface of the case thereby pressing the contact member and sliding the conductive protruding portions in accordance with the vertical motion in order to switch the contact terminals between an electrical connection state and an electrical disconnection state.
