Claims

[Claims for Utility Model Registration] (1) A stator having a fixed contact, a movable element having a movable contact that makes contact with and separates from the fixed contact, and a movable element that is slidably attached to the breaker casing and In a circuit switch having a push plate for opening and closing a movable member and a recess provided in the push plate for pushing a movable member, both sides of the U-shape are in contact with both sides of the movable member in the width direction. A U-shaped member that is fitted into the movable element in this manner, a movable element shaft that straddles and penetrates both sides of the U-shaped member, and a movable element shaft that is provided oppositely on both inner surfaces of the recess. and bearing recesses that respectively support both ends of the movable element shaft protruding from both sides of the U-shaped member. (2) Scope of Utility Model Registration Claim 1, in which the movable element has notches on both sides in the width direction of the intermediate portion, and the both sides of the U-shaped member are fitted into the respective notches. Described circuit breakers and disconnectors. (3) Both bearing recesses are also opened on the sides of the push plate, and both ends of the mover shaft supported by the two bearing recesses are prevented from falling off by the respective shunter housings. A circuit breaker according to claim 1 or 2 of the utility model registration claim. (4) Scope of the utility model registration claim in which the movable shaft is inserted into the U-shaped member and then the both sides of the U-shaped member are bent inward to press and fix the movable shaft against the movable member. The circuit breaker according to any one of Items 1 to 3.
