Abstract

Control device, especially for electromagnets and the like, comprising an electromagnet, which has a moveable keeper and an excitation solenoid, energised by a generator to and from which it is selectively connected and disconnected by a switch. The switch has a resistance with a modulus that is controllable by control means, and the resistance reduces the time constant of the circuit. <IMAGE>
