  • the known temperature-dependent switch comprises a housing with a metallic lower part and a metallic upper part.
  • a temperature-dependent switching mechanism is housed, which produces an electrically conductive connection between the lower part and the upper part of the housing as a function of its temperature.
  • the rear derailleur is equipped with a spring snap-action disc and a bimetal snap-action disc.
  • a so-called movable contact part which presses the spring disk against a stationary contact on the upper part, which forms the first contact surface, is welded to a centric support region of the spring snap-action disk. With its edge, the spring snap-action disc is supported on a second contact surface in the lower part of the housing, so that the electric current flows from the lower part through the spring snap-action disc and the movable contact part into the stationary contact and from there into the upper part.
  • the lower part of the housing is pot-shaped, it has on its inner side a circumferential shoulder on which rests the spring snap-action disc of the temperature-dependent switching mechanism.
  • the spring snap-on disc carries centrally the welded contact part, over which the bimetal snap-action disc is slipped, so that it rests loosely on the spring snap-action disc.
  • the upper part of the housing is designed as a lid, which rests on another circumferential shoulder of the lower part. Because the lower part and upper part of the housing are made of electrically conductive material is between them arranged an insulating film, the lower part and upper part of the housing electrically insulated from each other.

  • the known temperature-dependent switch is used to protect electrical loads from overheating.
  • it is mounted on the consumer to be protected so that it is in thermal contact with the consumer.
  • the supply circuit of the load is routed through the temperature-dependent switch by connecting a connection cable of the load to one of the external terminals of the switch and the other outside of the switch to the electrical supply circuit.
  • the bimetallic snap-action disc jumps into its high-temperature position in which it opens the switch, so that the supply circuit of the consumer is interrupted, which consequently can not heat up.
  • the bimetallic snap-action disc is mechanically free of forces below its transition temperature, wherein the bimetal snap-action disc is not used to conduct the current.
  • the bimetallic snap discs have a long mechanical life, and that the switching point, so the transition temperature the bimetallic snap disc, even after many switching cycles not changed.
  • the bimetallic snap disk can also take over the function of the spring snap-action, so that the switching mechanism comprises only one snap-action disc, namely the bimetallic snap disk, which then the movable Carries contact part and in the closed state of the switch also carries the power.
  • the bimetallic snap-action disc in the known switch In its low-temperature position, the bimetallic snap-action disc in the known switch is free in the derailleur, the spring-snap disc is supported with its edge on the second contact surface in the lower part.
  • the spring snap-action disc presses the movable contact part against the first contact surface, so that an electrically conductive connection between the self-conductive upper part and the likewise conductive lower part is produced via the fixed contact part and the spring snap-action disc.
  • a disadvantage of the known switch is the fact that at least the lower part of the housing must be made very precisely, so that the spring snap disc can be supported securely with its edge on the circumferential shoulder.
  • the lower parts of the known temperature-dependent switch turned parts, which means a high-precision manufacturing, but is associated with high production and unit costs.
  • the welded contact allows a simple and inexpensive installation of the known switch, because the contact part during assembly can not slip.
  • a disadvantage of the known switch is the fact that the welding of the contact part on the support area of the spring snap-action disc or the bimetal snap-action plate creates strains in the snap-action disc which can impair the mechanical function.
  • the DE 10 2007 014 237 A1 describes a temperature-dependent switch with a temperature-dependent switching mechanism, one of a frame having carried spring bar, which carries a movable contact part and a bimetallic snap disk.
  • the movable contact part is arranged at the free end of the spring bar, while the bimetallic snap disk is arranged approximately centrally to the spring bar and held captive with this via a rivet pin.

  • a pin is provided on the inside of the lid of the upper part of the switch, on which the spring snap-action disc and the bimetallic snap-action disc are plugged, after which the head of the pin has been thickened. A movable contact part does not have this switch.
  • the DE 21 06 132 A describes a temperature-dependent switch with a spring snap-action disc, which has an outer ring, from which extends inwardly a spring tongue, on which a movable contact part is welded.
  • a temperature-dependent switch which has a spring washer which cooperates with a bimetallic snap disk.
  • the spring washer has a central portion from which extend outwardly and downwardly three legs, with which the spring washer is supported inside in a housing of the switch.

  • the present invention has the object, the known temperature-dependent switching mechanism and the thus equipped temperature-dependent switch in such a way that a simple and inexpensive installation is possible without the mechanical function of the snap-action is impaired.
  • this object is achieved in that the support region is separated over a portion of its peripheral region by a gap of the snap disk, wherein the peripheral region is equal to or greater than 180 °, and further preferably, the contact part is welded to the support region.
  • this support area is now partially separated from the snap disk either before or after the welding of the movable contact part, for example via a gap or section corresponding to a circular section, then the internal stresses limit themselves to the contact area and do not extend over the entire snap disk.
  • a prior art spring-loaded snap spring can fail either upon opening of the switch or upon re-closure of the switch by providing such large counterforce to the snap-action bimetal snap-action that it does not dislodge the movable contact from the fixed one Contact can take off. It is also possible that the spring-snap disc after snapping into its concave shape, in which it is pressed by the bimetallic snap disk when the latter is heated to a temperature above their critical temperature, not automatically leave again and take the convex closed position can.
  • This separation can be done through a cut or gap, it being important that this separation results in that internal stresses in the support area do not or not completely radiate into the respective snap-action disc.
