Which type of switch is typically actuated by the trailing door in center opening systems?

In center opening systems, the switch that is typically actuated by the trailing door is the gate switch. This type of switch is designed to detect whether the door has fully opened or closed and plays a crucial role in ensuring the safe operation of the elevator system.

The gate switch responds specifically to the movement of the door, which allows it to help manage the timing of the elevator's operation. For example, once the trailing door fully opens, the gate switch sends a signal to the elevator control system, allowing the elevator to safely engage or disengage. This ensures that the elevator will not operate unless the doors are in a safe position, thereby enhancing passenger safety.

Understanding the function of the gate switch is important for anyone working with or studying elevator systems, as it plays an integral role in the overall safety mechanisms that prevent accidents and ensure a smooth operation.
