What does the door interlock system in an elevator ensure?

The door interlock system in an elevator is a critical safety feature that ensures the elevator doors remain securely closed while the elevator is in motion. This system is designed to prevent the doors from opening unless the elevator has come to a complete stop at a designated landing.

When the elevator reaches a floor, the interlock mechanism engages, allowing the doors to open only when the elevator is stationary. This is crucial for passenger safety as it minimizes the risk of accidents, such as someone stepping into an elevator shaft while the elevator is moving. By ensuring that the elevator doors cannot open unless the car is at rest, the interlock system helps to maintain secure operation and adherence to safety standards in elevator design and operation.
