ABSTRACT:
The electromagnetic relay of the present invention comprises a base (10), an electromagnet (20) disposed on the base, an armature (30) supported rotatably by the base, a movable spring (40) whose one end has a movable contact (41) and the opposite end is secured to the base, a fixed contact (51) disposed opposite to the movable contact, and a card (60). The card has a coupling part (61) to be coupled to the armature and an insertion hole (62) to which the one end of the movable spring is inserted, and it deforms the movable spring elastically in conjunction with a swing motion of the armature to selectively open or close a connection between the movable contact and the fixed contact. The movable spring has a U-shaped hook formed by bending the one end of the movable spring toward the opposite end side, and the hook can pass through the insertion hole while being pushed by an inner surface of the insertion hole and being deformed elastically, and an end of the hook is engaged with the card.
