Abstract
A relay includes a leaf spring for bearing an armature at a free end of a yoke, the leaf spring forming, first, a bearing plate lying against the yoke and, second, a pull-back spring applied thereto in one piece. The pull-back spring has a first section cut free from the middle of the bearing plate so that the bearing plate is subdivided into two plate sections on which the armature rests only at its lateral regions on its bearing edges. Further, the pulled-back spring as its free end cut arcuately roughly symmetrical to the center axis of the bearing plate to exert an approximately symmetrical pull-back force on the armature.
