Claims

[Claims for Utility Model Registration] (1) A movable contact that is rotatably supported and has a movable contact, a fixed contact that contacts and separates from the movable contact by rotation of the movable contact, and a movable contact that is rotatably supported and has a movable contact; A supported armature, a yoke disposed opposite to the armature, and a yoke suspended between the armature and the movable contact so that the movable contact can be rotated by a reversing operation as the armature rotates in the direction of the yoke. a reversing spring that applies contact pressure to the movable contact in the closed state while causing the contact to open;
An electric circuit penetrating between the yoke and the armature and causing the armature to be attracted to the yoke by an abnormal current, and an opening/closing means for opening and closing the movable contact, wherein one of the armature and the yoke is entirely A first side plate and a second side plate are formed in a U-shape, and a third side plate is formed on the other side in sliding contact with the surface of the first side plate, and an opposite side plate is formed so as to face the end face of the second side plate. A circuit switch or disconnector characterized by having a surface formed thereon. (2) The circuit breaker according to claim 1, wherein the end face of the second side plate is formed by forming a bent portion at the end of the second side plate.
