Abstract (en)
An armature holding structure in an electromagnetic relay uses a hinge-spring in the form of a wire spring (3). One end (31) of the wire spring (3) is held in a hole (131) in the yoke (13) of the electromagnet (1) and the other end (35) of the wire spring (3) is held in a hole (22) in the armature (2) so that the pivot support structure for the armature (2) at the end of the yoke (13) is maintained by the wire spring (3). Since the hinge-spring (3) is of wire, the holes (131, 22) for its ends (31, 35) can be small, so that these holes (131, 22) have little effect on the magnetic reluctance of the armature (2) and the yoke (13).
