PROBLEM TO BE SOLVED: To ensure desired switch operation feeling, even when the tightness of a space for housing a movable electrode and a fixed electrode is increased.SOLUTION: In the recess 2a of a case 2 mounted on a circuit board, a plurality of fixed electrodes 3a, 3b, and a movable electrode 5 are disposed. The movable electrode 5 can displace between a first position where the plurality of fixed electrodes 3a, 3b are in conduction with each other, and a second position where they are in non-conduction with each other. A press member 6 is disposed to cover at least a part of the recess 2a, and displaces the movable electrode 5 from the second position to first position by an external pressing force. The press member 6 has a peripheral portion 6a in contact with the case 2, a pusher 6b facing the central part of the movable electrode 5, and a thin part located between the peripheral portion 6a and the pusher 6b, and thinner than the peripheral portion 6a and pusher 6b. When the movable electrode 5 is at the second position, the thin part is facing the movable electrode 5 while sandwiching a gap. When the movable electrode 5 is at the first position, the thin part can be curved toward the outside of the case 2.SELECTED DRAWING: Figure 4 |
