  • the switch finger carrier 60 has, in addition to the shift finger portion 6, a guide pin 20, which is arranged with respect to the sleeve portion 60 opposite to the shift finger portion 6.
  • the guide pin 20 is received by a through hole 71, which extends from the outside to the step 67, so that the range of gradation 67 can be advantageously exploited without disturbing the attachment of the shift finger carrier 60 on the shift shaft 4. With its free end of the guide pin 20 protrudes into the link plate 18 and is forcibly guided there on the introduced backdrop, so that only the selection channel 68 and the switching channels 70 a and following can be traversed.
  • FIG. 15 shows a modified exemplary embodiment of the invention in a schematic three-dimensional representation from the side, with a part of the switching dome housing 4 being graphically suppressed.
  • the shift dome housing 4 in the figure 15 end stops 72, which are designed so that they limit the travel of non-illustrated shift rails.
  • the end stops 72 collar perpendicular to the sealing plane formed by the sealing region 32 are formed rectangular in cross-section parallel to the sealing plane and taper towards its own free end.
  • the width in the longitudinal direction of the Wegdomgephinuses 4 is adapted so that the end stops 72 can be used by multiple shift rails.
  • Two of the end stops 72 face each other in the transverse direction of the Wegdomgeophuses 4, so that the respective pair of end stops 72 provides a two-sided stop for the shift rails.
  • the end stops 72 are integrally formed on the Wegdomgeophuse, in modified embodiments, the end stops can also be used or used as separate components.
  • the advantage of the integration of the end stops 72 in the Wegdomgeophuse 4 is in a reduction of tolerances occurring with respect to the relative position of the shift rails and end stops in comparison to conventional designs.
