Claims

[Scope of utility model registration request]

(1) An armature that penetrates the coil bobbin of an electromagnet and is swingable at one end, a pair of magnetic pole parts facing to the side of the swinging end of the armature, and supporting the other end of the armature. A yoke having a hinge hole, and a permanent magnet fixed to a surface of one of the magnetic pole parts facing the armature and having a magnetic pole in the opposite direction, and when the armature is swung by the electromagnet. One side surface of the swinging armature end is configured to contact one of the magnetic pole parts via the permanent magnet, or the other side surface of the swinging armature end is configured to contact the other magnetic pole part. An electromagnetic relay characterized by:

(2) The electromagnetic relay as set forth in claim (1) of the utility model registration, characterized in that a card for operating a movable spring is fixed to the armature.
