Abstract:
PROBLEM TO BE SOLVED: To provide a two-stage switch device improved in durability.SOLUTION: The two-stage switch device includes an operation member, a support body, an actuator 4, a rubber dome 5, a first switch member 6, and a second switch member 7. The rubber dome 5 has: a first rubber dome 15 corresponding to the first switch member 6; and a second rubber dome 25 corresponding to the second switch member 7. The actuator 4 has: a first pressing surface 4p facing the first rubber dome 15; and a second pressing surface 4q facing the second rubber dome 25. The first rubber dome 15 has a first pressed surface 15p pressed by the first pressing surface 4p, and the second rubber dome 25 has a second pressed surface 25q pressed by the second pressing surface 4q. In a state in which the actuator 4 is not operated, the first pressing surface 4p and the first pressed surface 15p are substantially parallel to each other, and in a state in which the first switch member 6 is in an on-state, the second pressing surface 4q and the second pressed surface 25q are substantially parallel to each other.
