Claims

[Scope of Claim for Utility Model Registration] A movable contact having a long plate shape with movable contacts provided at both ends thereof, and a long hole into which the movable contact is attached while being biased by a contact pressure spring, and is driven by a movable contact. A contact opening/closing device having a movable frame made of an insulating material driven by a means, and a fixed contact provided with a fixed contact that comes into contact with and separates from a movable contact attached to the movable frame by the operation of the movable frame, the movable contact. and the movable frame are contact opening/closing devices whose abutting portions are formed in a concave and convex shape and whose positions are regulated relative to each other.
