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.

Abstract: An electromagnetic relay includes a fixed contact, a movable contact corresponding to the fixed contact, a movable element that retains the movable contact and moves in a contacting direction and a separating direction relative to the fixed contact, an axial core coupled to the movable element, a movable core coupled to the axial core to move in the contacting direction and the separating direction relative to a movement of the axial core, a driving part that drives the movable core in the contacting direction, an urging part that exerts force to the axial core in the separating direction, and a constraining part that constrains the relative movement of the axial core in the separating direction.
