An elevator hatchway door interlocking mechanism. The interlocking mechanism includes a first latch member movably mounted in a housing in the elevator hatchway which engages with a second latch member mounted on the hatchway door. A first contact assembly mounted in the housing engages with a second contact assembly mounted on the door when the door is closed. A third contact assembly movably mounted in the housing and operatively connected to the first latch member engages with a fourth contact assembly mounted on the second latch member. The elevator car is prevented from moving until the door is closed, the first and second latch members have engaged each other, and both sets of electrical contacts are made. Additionally, a manually operable releasing tool is provided for emergency or service use.
