Abstract

An electronic selector lever module for generating gear shifting signals for an automatic transmission of a vehicle. The swivel motion of the gear selector lever, within a main shifting path, is transformed into rotational motion for an angle sensor. The sensor is positioned on a printed circuit board and is actuated by a rotor. To guide the rotor relative to the angle sensor, the rotor either surrounds a rounded part of the printed circuit board or surrounds a rotor guidance which is mounted on the printed circuit board. The mechanical linking point is a short sleeve at a slider, which both belong to the rotor, needed for the shifting path motion, and which also drive the tilting lever for the transverse motion. The slider can be moved, relative to the rotor, along rails, either radially and directly at the rotor, or tangentially to the pivot point of the rotor.
