ABSTRACT:
The invention relates to an isolating switch system. The isolating switch system includes an isolating switch for interrupting a main line running between an electric power source and an electric consumer. The isolation switch is controlled in dependence on an ignition switch. The isolating switch system includes a signal generating unit, a signal detector unit and a signal processing unit. The signal generating device generates an electric signal that can be fed to the electric consumer and conducted to the ignition switch. The electric signal, in dependence on a switching state of the ignition switch can be conducted to the signal detector unit via a conduction path. The signal processing unit, upon detection of the electric signal, causes the isolation switching system to open or close the main circuit line. The electric signal generated by the signal generating unit is a pulsed signal.
