ことを特徴とする電磁継電器。[Scope of Claim for Utility Model Registration] Based on the excitation and demagnetization of the electromagnet, a movable contact piece is driven by a movable iron piece that rotates using the end of the yoke as a fulcrum, and the movable contact provided on this movable contact piece is used as a fixed contact. In the electromagnetic relay that connects and separates, the yoke and the movable iron piece are connected by a return member, and the return member is heated by heat transmitted through the movable iron piece due to abnormal heat generation of the movable contact and the fixed contact. An electromagnetic relay characterized in that it is formed of a shape memory alloy that recovers its shape so as to restore the movable iron piece.
