When are car doors considered closed using a keyed stop switch?

Car doors on an elevator are considered closed when they are 1" from closing when using a keyed stop switch. This measurement is crucial because it ensures safety and functionality in the operation of the elevator. The 1" distance indicates that the doors are near closure but still have sufficient space to prevent accidental entrapments.

This standard helps to comply with safety regulations and operational guidelines that protect passengers and ensure proper door alignment. By designating a specific distance for door closure, the system can effectively activate safety mechanisms, preventing the elevator from operating while doors are improperly closed. Understanding this distance is vital for elevator operators and maintenance personnel to ensure the safe and proper functioning of elevator systems.
