  • the setting shaft 8 is also axially displaceable relative to the cam disk 40 and the cam disk 55, but is coupled in a rotationally locking manner, so that they remain stationary relative to the base body 2 during the axial movement of the setting shaft 8.
  • the return spring 71 engages in the cam plate 40.
  • the design according to the invention results in an extremely compact construction of the switching device 1, since all the individual parts can be accommodated very closely to one another both in the axial direction of the adjusting shaft and transversely thereto.
  • the stop ring 67 is underneath due to the shape of the stop shoulder 69 the force of the return spring 71 compressed radially inwards so that it is constantly pressed into the annular groove 68 and cannot come out of engagement with the adjusting shaft 8.
  • the locking cam 65 ensures that switching the switching device 1 on can only be initiated by pressing the setting shaft 8.
