Laser security system:The Principles of Laser Security Systems:
There are three essential components to a laser security system:
A laserA detector A sensing electronics

Magnetic switchA magnetic switch is just like a light switch: it turns a circuit on or off depending on what position the arm of the switch is in. The only difference is that a magnetic switch is operated by a magnet, rather than your fingers.
