Patent ID: 7463126

Claim:
An electromechanical switch comprising: a base; a fixed contact disposed on the base; a fixed electrode disposed on the base; an actuator comprising a supporting portion disposed on the base, a beam portion extending from the supporting portion, and a movable electrode connected to the beam portion and facing the fixed electrode, wherein the beam portion is displaced in accordance with a displacement of the movable electrode by electrostatic attraction caused between the fixed electrode and the movable electrode; and a movable contact disposed on an end portion of the beam portion and facing the fixed contact so as to come into contact wit the fixed contact based on the displacement of the beam portion, wherein a slit is configured between the beam portion and the movable electrode, the slit is elongated between the beam portion and the movable electrode from a connecting portion that connects the beam portion and the movable electrode to an end portion of the movable electrode that is located on a side where the beam portion extends from supporting portion, the slit is configured such that the movable electrode is disconnected from the beam portion on the side where the beam portion extends from the supporting portion, the end portion of the movable electrode that is located on the side where the beam portion extends from supporting portion is freely movable with respect to the beam portion, and the movable contact and the supporting portion are linearly connected by the beam portion.
