What Is Reed Switch?
The Reed Switch is a magnetic switch that has two (on and off) switching modes, like a normal switch. The two pins are connected to each other by being in a magnetic field (for example, close to the magnet) and are disconnected by leaving that field.
These switches are used in open/close door detection sensors, seat belt sensors, collision detection sensors, etc.
Tip
Some magnetic switches are Normally Close. That is, when they are not in a magnetic field, the two pins are co...
