Abstract: A push-on switch includes a first contact plate, second contact plate, spacer, movable contact, and lid. The first plate has a projection at its center and a first terminal at its end. The second plate faces a face of the projection of the first contact plate and has an opening at its center and a second terminal at its end. The spacer is interposed between the first plate and the second plate for bonding them together. The movable contact is shaped like a dome and has a protrusion protruding downward and touches a top face of the second plate. The protrusion faces the projection of the first plate via the opening with a given space therebetween. The lid holds the movable contact and is mounted on the top face of the second plate. A push onto the movable contact reverses the movable contact downward, which allows the protrusion to touch the projection.

Abstract: A high waterproof compact push-on switch includes a first contact plate, a spacer, and a second contact plate laminated in this order. The first contact plate is substantially rectangular, and made of highly conductive flat sheet metal. The spacer is flat, rectangular, made of LCP resin, and has a circular center hole at its center. The second contact plate is substantially rectangular, made of highly conductive flat sheet metal, and has a circular central opening at its center. The spacer is thermocompression-bonded to the surfaces of the first and second contact plates so as to integrate them. On the second contact plate is provided a dome-shaped movable contact, which is covered with an adhesive protective sheet.
