Abstract
A chain brake which is manually adjustable into a cocked position and releasable by means of stored electric energy and a trigger, includes a permanent magnet circuit in which a movable armature is a part of a latch which keeps the brake in the cocked position. The permanent magnet has a coil exerting a counter directional magnetic field to the permanent magnet when it passes current. The holding force on the latch decreases and the brake is released when current from a capacitor passes through the coil.
