Actuating device for a parking lock

A method for forming an actuating device for selecting a gear of a shift-by-wire gearshift transmission, the method comprising:

• forming a housing;
• forming a selection lever movable along at least one shift gate between at least a driving position and a parking lock position;
• forming a mechanical transfer element for transferring the movement of the selection lever to the gearshift transmission for actuating the parking lock;
• and
• forming a coupling system arranged between the selection lever and the transfer element, wherein the coupling system comprises a slider element embodied to move in accordance with the movement of the selection lever,
• wherein the actuating device comprises an optical sensor arrangement arranged within the housing and comprising at least one transmitter/receiver pair having a transmitter and a receiver,
• wherein the slider element comprises a window structure such that when the slider element is in a first position corresponding to the driving position of the selection lever, the slider element interrupts an electromagnetic signal emitted from the transmitter or passes the electromagnetic signal through the window structure, and when the slider element is in a second position corresponding to the parking lock position of the selection lever, the slider element respectively passes the electromagnetic signal through the window structure or interrupts the electromagnetic signal.
