ABSTRACT:
A device is disclosed for sensing the rotary angle of a key-actuated lock system which contains a lock cylinder of a door or flap of a vehicle which is rotatable by way of a key. A follower is coupled to the lock cylinder via a driving coupling allowing a free-wheel rotational play and to a protection element of a lock and is rotatably mounted in a door interior. A switch-actuating part is rotationally coupled to the lock cylinder virtually free of play and is rotatable synchronously with the lock cylinder and a control switch which is switchable by the switch-actuating part at a specific rotary angle of the part and directly spatially adjacent thereto. The switch-actuating part is mounted behind the follower in relation to the lock cylinder on a carrier facing the interior of the vehicle and is fixed to the door or flap. A control switch is retained at least indirectly on the same carrier, and at least these two parts are sealed off relative to the door interior.
