Working Principle -
The reed switch operates using two ferromagnetic contacts sealed inside a glass tube. When a magnetic field is brought near the sensor the contacts attract and close the circuit. When the magnetic field is removed the contacts return to open state. This enables simple and reliable magnetic detection without external power.
