High Quality New Stainless Steel Elevator Button Elevator Cop Lop Hop Push Button

• Function and Role: It is installed at the elevator entrances on each floor to facilitate passengers to call the elevator. When passengers press the external call button, the elevator control system receives the signal and dispatches the elevator to operate. It can also display the current operating status of the elevator, such as the floor position and running direction, allowing passengers to understand the elevator's dynamics.
• Working Principle: The external call device is connected to the elevator control system through a communication line. After the button is pressed, the signal is transmitted to the control system. The control system arranges the elevator to respond according to the signal and the current status of the elevator, such as its position, running direction, and load, based on the dispatching algorithm. After the task is completed, the external call device returns to its initial state and waits for a new call instruction.
