Abstract
An electromagnetic relay including: an electromagnet; a movable spring having a movable contact; a first terminal to which one end of the movable spring is connected; a second terminal having a fixed contact opposite to the movable contact; an actuator that rotates by excitation of the electromagnet, rotates the movable spring, and causes the movable contact to come in contact with the fixed contact or to separate from the fixed contact; a nonmagnetic card to be attached to the actuator; a plurality of magnetic members that sandwich the movable contact and the fixed contact, and apply a magnetic flux to the movable contact and the fixed contact to extend an arc; and a permanent magnet attached between the magnetic members.
