Claims

[Scope of Claim for Utility Model Registration] A movable member in which a dome-shaped movable part that is pressed and driven by an actuator of an operator and a pressing part that protrudes from the center of the inner surface of the movable part are integrally formed of an elastic material such as rubber. an elastic sheet-like film on which the movable member is placed on the upper surface and a movable contact formed on the lower surface; and a fixed film fixed to the film at a predetermined gap and corresponding to the movable contact. A switch device comprising a fixed substrate on which a contact is formed, characterized in that the film is integrally provided with a platform-like protrusion that fits inside the movable part of the movable member, and the movable contact is formed on the lower surface of the protrusion. switch device.
