<p>This invention relates to a device for the interrogation of switching positions on a motor vehicle door lock comprising a closing cylinder which can rotate about its cylinder axis. A remote control sensor mechanism, which comprises at least one Hall sensor chip (3, 4) and an operating magnet (5), is provided for the interrogation of the switching positions. The operating magnet (5) is countersunk in the wall of a switching nut (1), which consists of a non-ferromagnetic material and which is attached to the closing cylinder. The Hall sensor chip (3, 4) is disposed on a component of the motor vehicle lock housing, wherein the arrangement is designed so that on the rotary movement of the switching nut (1) the operating magnet (5) can move past the Hall sensor chip (3, 4), emitting a signal, at an air gap distance (S).</p> |
