LATCHING SOLENOID WHICH UTILIZES RESIDUAL MAGNETISM FOR THE LATCH AND A CAPACITOR WHICH IS DISCHARGED TO DEGAUSS AND RELEASE THE LATCH

A solenoid is latched in an energized position by a residual magnetic field established by a pulse of current. A degaussing current is selectively applied from a capacitor to unlatch the solenoid. Fail-safe return to the de-energized position occurs when the supply of power is lost.
