Magnetically latching and releasing a voice coil actuator for controlling electrical switchgear. The voice coil actuator includes a voic coil magnet (220) 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 latching members (881,882) mounted to the voice coil assembly creates a permanent magnet circuit between the latching members an the voice coil magnet. The permanent magnet circuit maintains the position of the voice coil assembly relative to the voice coil magn 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, physi force to a member coupled to the voice coil assembly.

La présente invention concerne le verrouillage et la libération d'un actionneur de bobine acoustique pour contrôler un dispositif de commutation électrique. L'actionneur de bobine acoustique comprend un aimant de bobine acoustique (220) placé sur un axe longitudinal commun par rapport à un ensemble de bobine acoustique. Une bobine de l'ensemble de bobine acoustique exerce une force magnétique sur l'ensemble, en poussant l'ensemble vers l'aimant. Au moins une paire de membres verrouillants (881, 882) montée à l'ensemble de bobine acoustique crée un circuit d'aimant permanent entre les membres verrouillants et l'aimant. Le circuit d'aimant permanent maintient la position de l'ensemble de bobine acoustique par rapport à l'aimant de bobine acoustique même lorsque l'alimentation vers la bobine est coupée. Ce verrou peut être libéré en appliquant un courant dans la bobine ou en appliquant une force physique externe à un membre couplé à l'ensemble de bobine acoustique.
