PROBLEM TO BE SOLVED: To prevent impairment of the operation feeling, while responding to a severe request for miniaturization of a push switch.SOLUTION: A case 2 has a recess 2a. A plurality of fixed electrodes 3a, 4a and a movable electrode 5 are arranged in the recess 2a. The movable electrode 5 can deform elastically, in a first direction D1, between a first state where the plurality of fixed electrodes 3a, 4a are insulated electrically, and a second state where the fixed electrodes 3a, 4a are conducted electrically. A cover 6 covers the recess 2a. A press member 7 is arranged between the movable electrode 5 and cover 6. The press member 7 includes a first portion 7a and a second portion 7b. The first portion 7a is fixed to the inner surface of the cover 6. The second portion 7b is arranged closer to the movable electrode 5 than the first portion 7a. The width of the second portion 7b in a second direction D2 crossing the first direction D1 is narrower than the width of the first portion 7a in the second direction D2, and at a position where the central axis of the movable electrode 5 passes, the second portion 7b and movable electrode 5 come into surface contact, in both first and second states.SELECTED DRAWING: Figure 3 |
