    Abstract: Magnetically latching and releasing a voice coil actuator for controlling electrical switchgear. The voice coil actuator includes a voice coil magnet disposed on a common longitudinal axis with respect to a voice coil assembly. A coil of the voice coil assembly exerts a magnetic force on the voice coil assembly, thrusting the voice coil assembly towards the voice coil magnet. At least one pair of latching members mounted to the voice coil assembly creates a permanent magnet circuit between the latching members and the voice coil magnet. The permanent magnet circuit maintains the position of the voice coil assembly relative to the voice coil magnet, even when power to the coil is removed. This latch can be released by applying a current in the coil or by applying an external, physical force to a member coupled to the voice coil assembly.
