Embodiment Construction
[0047] The push button switch embodiment of the present invention is shown in the following Figure 1 to Figure 4 .
[0048] In the figure, the casing 1 is made of insulating material such as synthetic resin to form a square box shape, which is square in shape, has an opening on the top, and has a housing portion 1a inside. A central fixed contact 2a made of a conductive metal terminal member is provided at the center of the inner bottom surface of the housing portion 1a of the housing 1 so that it protrudes from the terminal member, and the upper side is exposed, and the central fixed contact 2a On the positions where the two sides of the two sides face each other, a peripheral fixed contact 2b, 2b similarly made of a conductive metal terminal member is provided, protruding from the terminal member, and the upper side is exposed. Further, external terminals 3a, 3b protruding outward are formed on opposing outer surfaces of the housing 1 .
[0049] The external terminals 3a,...
