Selector lever having actuating change of position

An operating device for selecting fixed gear ratios of a shift-by-wire gear shifting transmission, the operating device comprising:

• a housing base (14),
• a selector lever (2) being movable back and forth between at least a first detent position and a second detent position,
• a detent mechanism (9) comprising a spring-loaded selector lever detent element (11), the detent element (9) further having a notched contour (13) that releasably locks the selector lever (2) and a bevel contour (12) that returns the selector lever (2) back into the first detent position, the selector lever detent element (11) being brought into simultaneous overlapping with the notched contour (13) and also the bevel contour (12), and the notched contour (13) and the bevel contour (12) being displacable relative to each other in a direction of the selector lever detent element (11);
• the bevel contour (12) being essentially rigidly connected to the housing base (14), and the notched contour (13) being movable back and forth, relative to the housing base (14), between a first position near the detent element and a second position away from the detent element, the notched contour (13) being spring-loaded in the direction of the selector lever detent element (11), and in its first position overlaps the bevel contour (12);
• and
• the operating device comprising an actuating device (18) having an actuating block (17) for locking the notched contour (13) in its first position near the detent element, the spring-loading of the movable notched contour (13) being effectively weaker than the spring-loading of the selector lever detent element (11), and the first detent position of the notched contour (13) coincides with the first detent position of the bevel contour (12), when the notched contour (13) being located in its first position near the detent element.
