ABSTRACT:
A method of operating a drive circuit of a solenoid of an electromagnetic device including an armature, the drive circuit including switch means in series with the solenoid, comprising closing the switch means to achieve a high rate of current increase in the solenoid, opening the switch means when the current reaches a predetermined level and allowing the current to decay, the movement of the armature from a first to a second position being completed whilst the current is decaying and monitoring the decaying current using a sensing circuit which includes means responsive to a discontinuity in the decaying current flow when the armature reaches the second position.
