  • the adjusting bearing 37 can accommodate an adjusting support on which the adjusting member 46 is adjustable and fixable so as to be axially displaceable and resiliently loaded against the actuating plunger 45.
  • this adjusting support can then act on the pressure cam of the snap switch enclosing the supporting body 6 for actuation.
  • the invention relates, regardless of the training described, further to a switching device, in particular a temperature limiter for radiant heating units or the like, which, when a certain limit temperature is exceeded, automatically switches part or all of the installed power of the heating device provided with the switching device when a certain limit temperature is exceeded switches off and switches on again automatically after falling below a predetermined limit temperature.

  • Such switching devices can, for. B. according to DE-OS 35 40 414, 37 05 260 and 39 13 289, to which reference is made for further features, effects and advantages for the purpose of inclusion in the present invention.
  • the adjustment or the adjustment member for the signal switch which is further away from the temperature sensor than the circuit breaker is expediently provided or accessible in the region of the outside of the base facing away from the temperature sensor.
  • This adjusting member can then correspond to the adjusting member 46 according to FIG. 1 in terms of position and design.
  • This adjusting member is preferably provided on its bearing surface instead of an external thread with a thread-free smooth bearing or outer surface, so that it can only be adjusted by longitudinally displacing it along the likewise smooth-faced, substantially radially clearance-free bearing opening of the adjusting bearing 37.
  • the adjusting member can thereby be designed as a piece of rod or round wire piece produced only by cutting from a profile bar without further finishing.
  • the adjusting member 46 is then fixed in a non-detachable manner by welding, in particular laser welding, relative to the adjusting bearing 37 or the supporting part 21. This can also cause accidental Adjustment of the adjustment at a later time can be completely excluded.
  • the cover 41 expediently has latching members 40 in the region of its hood opening on the inside of its jacket wall, which are assigned counter-members 50 on the base 1 for resilient self-engagement.
