Claims

[Scope of utility model registration request]

In a keep relay in which the movable contact piece contacts a normally open contact or a normally closed contact to switch the contact by moving the tip of the movable contact piece in accordance with the swinging motion of the armature, a predetermined amount of contact is applied each time the armature swings. A ratchet mechanism including a ratchet that rotates by an angle, and a cam that is attached to a rotating shaft of the ratchet and rotates together with the ratchet to alternately move the movable contact piece to the normally open contact or the normally closed contact. and a keep relay in which a contact with which the movable contact piece contacts is switched by swinging the armature and changing the rotational position of the cam.
