ABSTRACT:
In a relay system, a flat yoke leg (21) is provided at which a plate-shaped armature (3) is seated via an armature spring (10). The flat yoke leg is arranged generally parallel to an axis of a relay coil core (1). An armature plate (3) has an end face seated at a broad underside of the yoke leg (21). A bearing section (12) of the armature spring lies against an end face of the yoke leg (21) and extends to lie flatly against the armature, to which it is preferably secured. A pre-stress section (13) of the armature spring extends axially beyond the bearing section (12) and is hooked and biased against a retainer peg (25) fashioned as an extension of the yoke leg. As a result thereof, the armature is urged against a bearing edge (22) at the underside of the yoke leg. Moreover, the armature is biased into a normal quiescent position with a predetermined force which is adjustably dependent on the deflectable position of the retainer peg.
