  • Patent number: 4492942
    Abstract: The relay exhibits a coil body on whose one flange an armature retaining element is integrated over elastic stays. A bar-shaped armature is secured in the frame-like armature retaining element, whereby the elastic flexural stays serve as a bearing for the armature. Additional fastening parts for the armature are thereby eliminated. A friction-free armature seating also thereby derives.

  • Patent number: 4490705
    Abstract: A relay has a bar-shaped armature which is seated at a location of one coil end over an armature carrier comprised of insulating material. For the purpose of seating, taut bands projecting in a direction of the rotational axis of the armature are integrated on the armature carrier, said taut bands forming suspension heads at their free ends. The armature carrier is engagably secured over said suspension heads between fork-shaped ends of retaining arms integrated on the coil body. Given movement of the armature, the taut bands are twisted so that a friction-free armature bearing is created.

  • Patent number: 4182998
    Abstract: A magnetically adjustable relay which may have an internally positioned sealed contact system is disclosed wherein the switching element of the contact system is elongated and has one end affixed to an elongated ferromagnetic adjusting plate. The adjusting plate is attached to the coil body by means of torsional cross pieces or bars. The position of the adjusting plate within the coil body can be adjusted by means of an exteriorly applied magnetic field which deforms the cross bars.
