ABSTRACT:
An electromagnetic relay has a tongue armature disposed inside a hollow coil body substantially along the coil axis, the tongue armature having a free end movable between two cooperating pole plates and a fixed end secured to a carrier disposed in a recess in a flange of the coil body substantially perpendicular to the coil axis. The carrier includes a pair of adjustment plates which are connected by means of torsion stays to fastening tabs, the carrier being connected to the coil body at the fastening tabs. Adjustment of the tongue armature is undertaken after assembly of the relay by the application of an external magnetic field to the adjustment plates, the displacement of which permanently deforms the torsion stays so as to suitably position the tongue armature.
