Abstract

A contactor provided for AC is DC fed, the coil 1 being in series with a transistor 5 operating as a chopper, and a resistor 7. At the measuring point 8, the current in the coil is compared with reference values. Each cycle of operation of the contactor comprises a feed period and a pause. At the end of the pause, a measurement of the current in the coil enables the position of the armature to be determined. <IMAGE>
