For better understanding, attach the installation position map of refrigerator door magnet. Some large refrigerators will install magnets around the doors.
The refrigerator door is closed by reed switch, the magnet is installed on the door, and the reed sensor is connected to the fixed frame hidden behind the outer wall of the refrigerator. When the door is opened, the reed sensor can't detect the magnetic field, which causes the LED bulb to light up. When the door is closed, the sensor detects a suitable magnetic field and the LED goes out.
