ACCess Interlocks - Type D

In the Type D interlock, the main body is typically attached to a door or hatch that swings open. The latch block is typically bolted to the door frame. When the key is turned and the door is opened, the main body and latch block are separated causing the key to be trapped and the locking bolt to be held in the withdrawn position. The key is always held whenever the two parts are separated. When the door is properly closed, the lock body seats fully against the latch block, releasing the locking bolt. The operating key can now be rotated to extend the locking bolt into the latch block. After the locking bolt is fully extended, the operating key may be removed.
