The device comprises an output gearwheel (6), a gear cover (4) having a plastic sleeve open toward the output gearwheel (6) and a park position switch having first contacts mounted for rotation and second contacts fixed to the gear cover (4) and a driving means. The invention provides that the sleeve is embodied as a contact sleeve (8) having contact tracks (31b, 53a, 31), particularly along the inner surface of the contact sleeve (8). To enable sliding contact on rotation, the cylindrical member (10) of a driving disk (9) extends into the contact sleeve (8).
