Definitions

  • the invention relates to a position switch with a Pivot lever drive, the one mounted in a drive housing Shift shaft and attached to this actuator having.
  • a position switch of the above type in which the Actuator be positioned against rotation can be that the safety function "forced opening" in selectable small angular ranges of the position of the actuating element is ensured to the housing. Another goal is it, the actuator while retaining its function to turn 180 °.
  • the use of Plastic or metal in any variation of the individual Components may be possible.
  • the contact forced opening condition is that at the switch operation the contact separation as a direct result a fixed movement of the operating part of the switch via non-resilient parts, i. amongst other things also the connection between the switching shaft and the actuating element is positively stable.
  • the switching shaft provided with a partially circumferential outer toothing is to which the actuator with its adapted thereto Internal toothing is plugged form-fitting.
  • FIG 1 a position switch 1 with a pivot lever drive 2 shown.
  • the pivot lever drive 2 is according to 2 essentially of a drive housing 3 a Shift shaft 4 and one executed here as a shift lever 5 Actuator assembled.
  • the shift shaft 4 is in Drive housing 3 mounted and protrudes with its one end, the provided with a partially circumferential outer toothing 6 is out of the drive housing 3 (see FIG 5).
  • the Attachment of the shift lever 5 takes place on the shift shaft 4 with a screw 11.
  • a circumferential approach 12 on the shift lever 5 covers the drive housing 3, whereby the shift shaft 4 is protected against external influences.
  • the shift shaft 4 with drive housing 3 and the required actuators, e.g. the shift lever 5, can meet the technical requirements accordingly made of plastic or metal be.
  • the switching shaft according to the invention 4 for metal and plastic encapsulated position switches can be dispensed with an expensive steel shaft.
  • molded Bushings, e.g. from measurement, in metal drive housing can be omitted.
  • the switching shaft 4 can be inexpensive further actuators in appropriate Apply way.
