Abstract

An armature support for a hinged relay has beveled bearing surfaces which force the armature, when the armature is displaced, into a rotational movement about a center of a switch contact. In this manner, structural tolerances of the hinged relay, as well as axial play in the armature support, are balanced out to avoid a switch contact displacement.
