WIPO Patent Application WO/2006/006557

Kind Code:

A1

Abstract:

An electromagnetic relay comprising a base (10), an electromagnet (20) arranged on the base, an armature (30) rockably held on the base, a movable spring (40) having one end provided with a movable contact (41) and the other end secured to the base, a fixed contact (51) arranged oppositely to the movable contact, and a card (60). The card has a part (61) coupled with the armature, and a hole (62) into which one end of the movable spring is inserted. The movable spring is interlocked with the rocking of the armature to deform resiliently, thus opening/closing the movable contact and the fixed contact selectively. The movable spring has a pawl (400) formed by bending one end thereof toward the other end into a U shape, and the pawl can be passed through the insertion hole while being pressed against the inner surface thereof and deformed resiliently before the forward end of the pawl engages with the card.
