Functioning Reed Switch: the reed switch is an electrical switch operated by an magnetic field. It consists of a pair of ferromagnetic flexible metal reeds contacts in a hermetically sealed glass envelope. The contacts are usually open, closing when a magnetic field is present, or they may be normally closed and open when a magnetic field is applied. The switch may be actuated by an electromagnetic coil, making a reed relay or by bringing a permanent magnet near the switch. When the magnetic field is removed, the reeds in the reed switch return to their original position.
