2. Description of the Related Art A conventional technique will be described with reference to FIGS. FIG. 3 is a perspective view of a conventional push-on switch, and FIG. 4 is a side sectional view of the same. According to the figure, 1 is a plastic case having an opening on the upper side, and on the bottom surface thereof is an outer fixed contact integrated with a circuit connecting terminal 2 and a center integrated with another circuit connecting terminal 3. Fixed contact 5
Are provided by insert molding. Reference numeral 6 denotes a dome-shaped movable contact made of an elastic metal thin plate, the outer peripheral end of which is in constant contact with the outer fixed contact 4. Reference numeral 7 denotes a sealing film made of a flexible insulating sheet. By sealing the inside of the case 1 by adhering a portion in contact with the open end surface of the case 1 with an adhesive, the central portion of the sealing film is pushed. The sealing film 7 is made of a flexible thin film so that it can be bent downward.
