- the aisle selector rod 1 and axis 6 are oriented from left to right in the illustration shown.
- the aisle selector rod 1 On its circumference, the aisle selector rod 1 has a connecting geometry 3 which has a maximum elevation 4 which is at the greatest distance from the axis 6.
- a switching element 2 is shown in a sectional view.
- the switching element 2 has a correspondence geometry 7, which is formed within the switching element 2.
- the switching element 2 in particular the
- Correspondence geometry 7 an opening 5 into which the alley selector rod 1, in particular the connection geometry 3, is inserted.
- the opening 5 is designed as a through hole, so that the alley selector rod 1 penetrates the switching element 2 through the opening 5.
- the opening 5 is formed as part of the correspondence geometry 7.
- the opening 5 in FIG. 1 a has a larger inner diameter on the right side of the switching element 2 than on the left side of the switching element 2. This inner diameter does not extend rotationally symmetrically about the axis 6.
- FIG. 1 b the 90 ° 1 a is rotated, the opening 5 on the right side of the

- the invention is not limited to the embodiments described above. Rather, further embodiments can be formed by combining different features of the individual embodiments. Individual features can also be modified.
- the opening 5 of the correspondence geometry 7 can also be designed without a through hole. Instead, only a blind hole could be formed, in which case the alley selector rod 1 can no longer be guided through the switching element 2. It is also conceivable to design the correspondence geometry 7 completely without opening 5. Instead, it could
- Correspondence geometry 7 may be formed, for example, on the surface of the right side in FIG. 1 a of the switching element 2, the correspondingly configured connection geometry 3 being designed to form a connection according to the invention with the correspondence geometry 7.

- the assembly takes place here, for example, in that the spring of the switching element 2 is brought into engagement with a groove of the alley selector rod 1, which extends parallel to the axis 6 and runs out at one end of the alley selector rod 1. From this end, the switching element 2 can be plugged with the spring onto the alley selector rod 1 and moved along this groove to the position along the axis 6 at which it is to be fixed. At this position, the partially circumferential groove adjoins the groove that runs parallel to axis 6. Once the spring has reached the position, the fixation is again carried out by a rotation Y.
