How do interlock systems enhance elevator safety?

Interlock systems play a crucial role in enhancing elevator safety by ensuring that the elevator does not operate unless the doors are securely closed. This mechanism is designed to prevent accidents caused by the doors being opened while the elevator is in motion, which could result in serious injury to passengers. When the doors are not properly aligned or closed, the interlock system activates, thus inhibiting the operation of the elevator until it is safe to do so. This feature is vital for maintaining the safety of passengers and ensuring the proper functioning of the elevator system, as it prevents situations where someone might attempt to enter or exit the elevator while it is moving.

While controlling the elevator's speed, providing power backup, or allowing for manual control can be important aspects of elevator operation, none of these functions directly prevent the movement of the elevator in response to door status, which is a primary function of interlock systems.
