ABSTRACT:
A compact, thin switch of a simple contact structure to be operated for switching operations by an external pressure comprises a base, four stationary contacts arranged on the base and isolated from each other, a curved, self-resetting first movable contact plate formed of a conductive spring material, and mounted on the base, and a curved, second movable contact plate formed of a conductive spring material, and put on top of the first movable contact plate. The first movable contact plate is disposed opposite to the stationary contact with one end thereof in permanent contact with the stationary contact and the concave surface thereof facing the stationary contact so as to be brought into contact with the stationary contact, the second movable contact plate is disposed with its concave surface in permanent contact with the convex surface of the first movable contact plate, one end thereof in permanent contact with the stationary contact and the other end thereof in contact with the stationary contact so as to be able to be separated from the stationary contact make the first movable contact plate and the second movable contact plate yield to curve convexly in the opposite direction is applied to the second movable contact plate so that the first movable contact plate comes into contact with the stationary contact and the other end of the second movable contact plate is separated from the stationary contact.
