Abstract
An armature-mounting arrangement for a hinged-armature relay includes a yoke (3), an armature (1) positioned at an end portion of the yoke, and an armature holding spring (2) which has at least one switching contact thereon and which is mechanically coupled to the armature. The armature holding spring is formed as one piece with a return spring (5) for the armature and also with spring hooks (4). Each of the spring hooks has a first portion (4a) lying substantially flat on an outer side of the armature and a second portion (4b) extending from the first portion about the armature and lying almost flat against an outer surface of the yoke. This armature-mounting arrangement is a particularly uncomplicated and cost effective structure and its operation is also not particularly sensitive to fabrication tolerances of the armature and the yoke.
