Claims

[Claims for Utility Model Registration] A normally closed fixed contact spring having a normally closed fixed contact; a normally open fixed contact spring having a normally open fixed contact; and first and second leaf spring parts branching from a base. A normally closed movable contact is provided on one side of the first and second leaf spring portions, facing the normally closed fixed contact, and a normally closed movable contact is provided on the other side, facing the normally open fixed contact. a twin movable contact spring having a normally-open movable contact and provided with a return force so that the normally-closed movable contact comes into contact with the normally-closed fixed contact; and the first and second leaf spring portions when driven by the relay. a moving member that presses the first and second plate spring portions in the direction of the normally open fixed contact spring to bring the normally open movable contact into contact with the normally open fixed contact; The contact portions of the member with the first and second leaf spring portions are formed on the same surface, and when the relay is restored, the contact portions of the first and second leaf springs with the movable member are formed on the same surface. , the first and second leaf spring parts are formed to be disposed at different distances from the contact part, so that the first leaf spring part is normally opened by the pressure of the moving member during driving. An early make characterized in that an operation sequence is given such that after the movable contact and the normally open fixed contact come into contact, the normally closed movable contact of the second leaf spring part separates from the normally closed fixed contact and becomes an early make break.・Small relay for break.
