If the conductive material fails against the coupling half 3, the control voltage is isolated and the electrical energy is measured. With the slip rings, a carrier 8 is firmly connected, preferably an electrolytic capacitor. In this carrier 8, a Schleifkon voltage for the electrical switching contact 9 described is mounted, which is applied to a spring 10.
