  • Movable contact carriers consist of a Combination of molded plastic parts and metal parts are.
  • This contact lever carrier has a central part that consists of a base body and there is at least one additional body that can be attached to it, the bearing arms being fastened on both sides to the central part are.
  • Both of the movable contact carriers mentioned are more conventional Construction composed of several individual components. Such constructions are simple and expedient, but result from many individual tolerances formed, relatively large width tolerance, namely a mutual Sheet tolerance and a tolerance of the central part. Added to this is the fact that tension arms are carried over with metal support arms may occur.
  • registration number 199 48 692.1 proposed a complete contact carrier in one piece as a multifunctional part made of a, in particular fiber-reinforced, To manufacture plastic. This also points special lateral guide surfaces, which with counter surfaces of the switch housing interact. This will in spite of what is required in the case of plastic constructions larger dimensions, comparatively small overall dimensions reached.
  • the invention has for its object a movable To create contact carriers that have the mechanical strength of a Metal construction with the advantages of plastic technology combines.
  • the Movable contact carrier for receiving contact levers for Low-voltage circuit breaker using the side bearing arms is pivotally mounted for switching on and off an insulating body with enclosed by the insulating material metallic reinforcement elements to increase the mechanical Firmness exists.

  • the side bearing arms of the contact carrier can be made thinner than such made of pure plastic. If they are thicker than those made of metal, there is an advantage in that there is only one tolerance, namely that of the outside Plastic body. The individual tolerances are balanced inside and the external tolerance is determined only by the shape. This can improve the overall width of the contact carrier can be adjusted to the chamber width of the pole and both Parts, the fixed chamber and the movable contact carrier can be better coordinated. It has to no space for fasteners, such as protruding screw heads or the like, are kept free and by the smooth side walls of the contact carrier result in a good one Tightness against the passage of switching gases in this Area.
