ABSTRACT:
The relay has an U-shaped and E-shaped yoke member with an interconnecting permanent magnet. An U-shaped armature rocks between the yoke members and is held by springs between them. The springs are attached with one end each to the E yoke member; in order to prevent sliding of the armature or yoke parts on changing position, the springs are constructed to permit resilient length compensation and are attached with the other end to the armature beyond a temporary fulcrum on the U yoke member.
