Abstract
A push-on switch includes a movable contact which has a projecting segment permanently connected with an outer contact and which is accommodated in a recess of a switch enclosure. A sheet with a center through hole for the movable contact is placed on the switch enclosure. The push-on switch also includes a metal cover with a cover terminal. The metal cover is attached to the switch enclosure such that a pressing segment faces a disc segment of the movable contact corresponding to the position of the center through hole with a predetermined vertical gap between the pressing segment and the disc segment. When a very low and weak force is applied on the pressing segment, the pressing segment comes into contact with the disc segment to change the state of a first-stage switch.
