It is preferably such that the electrical switch 6 of the detection device 3 is connected directly in the load circuit of an associated electric drive, an associated electric lamp o. The like. Then the electric switch 6 switches according to load current. But it may also be advantageous that the electrical switch 6 is not connected directly, but indirectly, namely via a relay or an amplifier stage in the load circuit of a corresponding consumer.
