1. Sensor detection: IPU security door lock switch detects the status of the door through the built-in sensor. Common sensors include magnetic sensors, infrared sensors, or mechanical switches. When the door is closed, the sensor detects the position of the door.

2. Lock signal: When the sensor detects that the door is closed, it sends a lock signal to the control circuit. This signal tells the control circuit that the door is locked and triggers the action of the lock.

3. Electromagnetic lock: The control circuit usually contains an electromagnetic lock, which is used to keep the door locked. The IPP electromagnetic lock is composed of a coil and an iron core. When powered on, the current in the coil will generate a magnetic field, which will attract the iron core to the lock body and realize the lock of the door.

4. Open the door to unlock: When someone needs to open the door, the switch will trigger the control circuit to send an unlock signal. The control circuit stops supplying power to the magnetic lock, causing the magnetic field to disappear, the core to lose its attraction, and the door to be opened.

5. Security protection function: Security door lock switch usually also has some additional security protection functions, such as shield monitoring, detection of door closing speed. These functions ensure the safety and reliability of the safety door during use.
