An electric clutch system for a mortise-type security lock is provided. The clutch system includes one or more magnets disposed in one hub of a mortise-type lock. The magnet is recessed and disposed below the interior surface of the hub that engages the opposing hub of the mortise-type lock. The opposing hub includes one or more spring-biased armatures. Upon the application of current to the magnet, the armature is drawn toward the magnet resulting in a coupling-type connection between the two hubs so that rotation of the exterior handle will open the door.
