ABSTRACT:
An electromagnetic relay has a flat armature which is normally biased away from a pole plate by a bearing spring attached to the armature which is mounted in a recess in a yoke plate, and is clamped thereto. A particularly low friction mounting is achieved by specific selection of the ratio of the distance between the bearing point of the armature and the clamping point of the bearing spring, to the distance between the point of attachment of the bearing spring to the armature and the bearing point.
