Abstract: An arrangement for controlling the current in a circuit having a source of current connected with an inductive device and a load. A switching member is provided in the circuit, this member being controlled between on and off conditions by a triggering element joined to a series circuit which includes the inductive member, an additional inductance and a control member. The control member establishes the rate at which the additional inductance becomes saturated when the switching member is turned off. The state of saturation is employed to operate the switching member thereby controlling current flow to the load.
