ABSTRACT:
A door interlock includes a pivot arm having a door lock position, a door unlock position, and a latch recess. A latch has a door lock position against the pivot arm, a door unlock position releasing the pivot arm, and a latch projection. A latch operating solenoid is the only solenoid mechanically linked to the latch. A capacitor is supplied by a power supply and is arranged to pulse the latch operating solenoid without pulling down the power supply. The pulsing of the latch operating solenoid by the capacitor causes the latch operating solenoid to move the latch projection of the latch into and out of the latch recess of the pivot arm so that a door is locked and unlocked.
