Abstract
In an electrical function group, a useful circuit having electrical module units is electrically connected via a plug-type connector. The plug-type connector is equipped with a longer and with a shorter contact pin, so that the shorter contact pin separates first when the plug-type connector comes apart. The longer contact pin is a useful contact that closes the useful circuit and the shorter contact pin is a signal contact that closes a signal circuit. The signal circuit contains a monitoring arrangement that generates an alarm when the signal circuit is parted by the signal contact. As a result thereof, an incipient parting event of the plug-type connector is recognized before the useful circuit is separated.
