Abstract

An electromagnetic relay has an armature (10) which is supported such that it can pivot about a central axis and, in its two limit positions, rests with its two ends against in each case opposite ends (19, 20) of a yoke so that a three-point support is produced in each limit position. Each armature end is allocated at least one contact system (21...24) with a stationary contact (28) and a contact spring (26) which can be moved by the armature (10) via an operating device (31, 32). The contact springs (26) are pretensioned in a laterally asymmetric manner with respect to the armature longitudinal axis (L) in such a manner that the positioning forces (F1, F2) exerted by them on the armature (10) in its two limit positions are directed in the same direction at right angles to the armature longitudinal axis (L). In contrast, the armature support is installed such that it absorbs a supporting force (K) which is parallel to but opposes the positioning forces (F1, F2). In consequence, when the armature (10) is pivoted from each of its limit positions, simultaneous release of both armature ends from the yoke ends (19, 20) is ensured. <IMAGE>
