Because the universal character of the motor vehicle lock and in particular of the associated lock housing requires that use on a driver's door and, for example, on a rear side door as well as on a passenger door must be covered. For this reason, the first switch socket is typically designed as a lock cylinder switch socket, while the second switch socket is generally a child safety switch socket.
