ABSTRACT:
A slide switch S includes a sliding member 1, a fixed contact 10 of a pole plate 7, a movable contact plate 2, a spring 12 interposed between the sliding member 1 and the movable contact plate 2, pawl portions 121, 122 formed on wall surfaces 111, 112 on both sides of the sliding member 1, and slots 41, 42 engaging with and anchoring the pawl portions 121, 122 and functioning as a guide and formed on both leg pieces 211, 212 of the movable contact plate. The movable contact plate 2 is bent and expanded outward on the side of an end portion 221 of the leg piece 211 with respect to the portion where the slot 41 is formed. This slide switch construction eliminates damage between the movable contact plate of the slide switch and the pawl portions engaging with, and anchoring, the movable contact plate, and results in a smoother operation of the switch.
