Abstract
An electromagnetic relay includes an electromagnet part, an actuating part, a contact part and a base for holding the electromagnet part, the actuating part and the contact part. The contact part includes a pair of fixed plates having one end fixed to the base and the other end to which a fixed contact is attached, a pair of movable springs having one end fixed to the base and the other end to which a movable contact is attached, and a connecting portion extending between the movable springs and electrically connecting the movable contacts to each other. The actuating part is actuated so as to press only a part of the movable springs inside an area defined between longitudinal axes extending between one end and the other end of the movable springs through the movable contact, when the contact part closes.
