Door Control Switches are devices that control the safety of work elevators. When delivering or receiving passengers in an elevator, when the landing door is not closed or cannot be closed normally, the device will automatically control the landing door to close to ensure the safety of elevator operation. The function of the elevator landing door automatic closing device is to avoid safety accidents and protect people's lives. According to statistics, many elevator accidents that have occurred both domestically and internationally in recent years are caused by elevator floor doors not being closed or not fully closed. Therefore, the automatic closing device of elevator floor doors is an important means to improve the safety performance of elevators
Generally speaking, the automatic closing device for elevator floor doors mainly consists of a controller, an actuator, sensors, etc. The controller can receive external signals to determine whether the floor door is closed and control the actuator to perform door opening and closing operations. Sensors are used to detect the status of elevator floor doors, ensuring that they can be closed properly. In addition, in order to meet the safety requirements under different operating states, Door Closing Limit Switches also need to have the function of repeatedly opening and closing to ensure the safe and reliable operation of the elevator.
