The auxiliary switching cam 25 for the locking ball 24 is pointed. The intermediate switching positions are achieved through the auxiliary switching curve designed in this way for the intermediate switching positions in the form of a circular arc on the pivot point of the switching position. Paragraphs 26 and 27 serve as the Be-Kruit-Weg characteristic curve of the main detent element and 15 limit stops to define the intermediate position of the main switching curve to define the middle detent switching positions. After paragraphs 26 and -7 adjustment and the work detent positions only from the running, the auxiliary switching curve runs again in the middle switching positions in the arc of a circle is influenced, which inevitably continues.
