とするシーソスイツチ。 A handle that has an operating surface exposed on one side of the case and is supported by the case so as to swing relative to the case, a fixed terminal that is fixed at a fixed position on the case and has a fixed contact, and a fixed terminal that is fixed at a fixed position on the case. A support terminal placed apart from the terminal, a movable contact having a movable contact that is swingably pivoted to the support terminal and moves into and out of contact with the fixed contact as it swings, and one end connected to the handle. A movable seesaw switch is provided with a reversing spring, the other end of which is connected to a movable contact, which swings the movable contact as the handle swings, and which is most compressed at an intermediate position in the swing range of the handle. An on-stopper and an off-stopper are provided on the side edges of the contact so as to project apart from each other, and a protrusion is provided on the inner peripheral surface of the case to be inserted between the on-stopper and the off-stopper. A seesaw switch comprising: an on-stop surface that contacts an on-stopper at a position where the movable contact contacts a fixed contact; and an off-stop surface that contacts an off-stopper at a position where the movable contact is separated from the fixed contact.
