ABSTRACT:
Disclosed is an electromagnetic relay whose armature assembly is protected against jarring impacts. The armature assembly is tiltably supported in a recess stamped out in an end portion of the magnetic yoke of the relay. Lateral inner walls of the recess are formed at their free ends with shoulders for engaging a flat biasing spring of the armature assembly. At least one lateral portion of the magnetic yoke delimiting the recess is formed with a constricted region, for example with a cutout in a corner between an inner wall and the bottom wall of the recess. The constriction permits the bending of the lateral projection into an open condition in which the corresponding shoulder is out of the way during the insertion of the armature assembly into the recess. Upon the insertion, the lateral projection is bent toward the armature until the corresponding shoulder overlaps the armature edge.
