Claims

[Claims for Utility Model Registration] A frame that forms a magnetic path, a switching part that brings a movable contact into contact with and separates from a fixed contact, and a switching part that is attached to the frame and that operates the switching part by excitation and demagnetization. An electromagnetic relay comprising an excitation coil that switches the movable side contact, wherein the excitation coil is configured to move toward the forward side along a direction of magnetic flux generated by the excitation coil when the excitation coil is excited, and to demagnetize the excitation coil. Sometimes, a plunger that moves to the backward movement side is housed by a return spring provided between the frame, and the switching part has at least two movable parts that are switched by the forward and backward movements of the plunger near both operating ends of the plunger. An electromagnetic relay characterized by having a side contact.
