装置。[Scope of Claim for Utility Model Registration] A dome-shaped movable part that is pressed and driven by an actuator of an operator and a cylindrical part that hangs down from the inner surface of the movable part and has a movable contact on its lower end surface are made of an elastic material such as rubber. A switch device comprising a movable contact member integrally formed with a movable contact member and a fixed substrate on which the movable contact member is placed and a fixed contact corresponding to the movable contact is formed, wherein the movable contact member has a dome-shaped first a buckling portion, a second buckling portion integrally connected to the bottom edge of the first buckling portion and expanding, and the movable contact hanging from near the top of the second buckling portion and on a lower end surface thereof. 1. A switch device comprising a cylindrical portion having a cylindrical portion formed therein, and having a different strength between the first and second buckling portions to generate a time difference between the buckling points of the first and second buckling portions.
