Reed Switch (100V - 0.5A)
The reed switch[i] is an electrical switch operated by applying magnetic field. Reed switch used to control the flow of electricity in a circuit. They are made from two or more ferrous reeds encased within a small glass tube-like envelope, which become magnetized and move together when a magnetic field is moved towards the switch. The switch effectively works like a gate, or a bridge, in an electric circuit so when the two reeds are in contact, electricity can flow around the circuit operating a device.
Reed switch can be used as a sensor, counter, limit and so on. Also mainly used in door magnetic, magnetic window in the security system
