What is the purpose of a door interlock system in elevators?

The purpose of a door interlock system in elevators is to ensure that the elevator can only operate when the doors are securely closed. This is a critical safety feature that prevents the elevator from moving while passengers are entering or exiting. If the doors are not completely shut, the interlock prevents the elevator from being called or moved. This mechanism is essential for preventing accidents, such as a passenger becoming trapped or the elevator moving while someone's still inside or near the door area.

The interlock system plays a fundamental role in elevator safety protocols, ensuring that only when the doors are properly aligned and shut can the elevator respond to commands. This adherence to safety standards is crucial in protecting passengers and maintaining the operational integrity of the elevator system.
