ABSTRACT:
An electronic door lock/unlatch control in which the latching mechanisms latch mechanically upon door closing and include electric motor driven unlatching mechanisms but no mechanical locking apparatus. Locking is accomplished electronically for each door by a flip-flop which enables or disables a power MOSFET connected in series with the unlatch motor and unlatch switch for the door and an electric power source. The flip-flop for each door also controls lock status indicating lights. A rear door unlatch disable switch is included additionally in series with the rear door unlatch switch to allow operator disabling of the rear doors.
