The reed switch contains a pair (or more) of magnetizable, flexible, metal reeds whose end portions are separated by a small gap when the switch is open. The reeds are hermetically sealed in opposite ends of a tubular glass envelope. A
magnetic field (from an electromagnet or a permanent magnet) will cause the reeds to come together, thus completing an electrical circuit.
