A circuit means is disclosed for aiding the collapse of an electromagnetic field in order to remove energy stored therein and thus to hasten movement of a movable member whose position is controlled by the strength of the electromagnetic field. In particular, an electronic device is used to provide a repeatable, uniform, rapid, controlled energy dissipating circuit path. By dissipating the energy stored in the electromagnetic field through a zener diode, uniformity of field collapse is assured, good repeatability is provided and actuation frequency of the field is increased.
