Definitions

  • a push-button or lever mechanism is provided between the external control elements and the internal switching elements. It is problematic to seal the internal switching elements from the external operating elements. This is done through complicated seals.
  • the wheel segment is provided as an operating part.
  • the wheel segment is connected to the deflection wheel via the connecting rod.
  • the connecting rod is thin. It can therefore be sealed by a simple sealing element.
  • the deflection wheel has at least one translation segment, via which continuously adjustable switching elements are driven.
  • the invention therefore not only enables the switching elements to be switched on and off, but also the stepless or gradual adjustment of switching elements.
  • the end of the connecting rod 8 facing away from the wheel segment 4 is connected to a deflection wheel 3.
  • the deflection wheel 3 is pivoted about its axis 31 in proportion to the pivoting angle of the wheel segment 4.
  • Electrical switching elements for example a microswitch 7, can be switched both at the end of the pivoting movement and in intermediate positions via the deflection wheel 3 and a translation segment 2 (switching cams).
  • the deflection wheel 3 thus enables switching elements, in the exemplary embodiment, a potentiometer 6, whose drive angle is greater than the adjustment angle of the wheel segment 4, to be infinitely or stepwise adjustable.
