A reed switch is a mechanical electrical switch having a pair of ferromagnetic contacts in either a normally-open or normally-closed configuration. Reed switches are a low voltage switch, generally in the one watt range. A reed switch comprises confronting contact points including magnetic wire members and a glass tube enclosing those points and performs open/close operations of the contact points by applying a magnetic field from the outside of the glass tube. The contacts are normally spaced apart when they are in close proximity to a magnet and they are moved toward each other to close the switch when the magnet is moved a certain distance from the switch. In a reed switch, two lightweight metallic rods are hermetically sealed through opposite ends of an elongated hollow glass tube in such a manner that they extend substantially parallel to the longitudinal axis of the tube. In the presence of a magnetic field, the contacts of a normally-open reed switch will close, while the contacts of a normally-closed reed switch will open. Reed switches are commonly used for sensing the position of a mechanism the movement of which is to be monitored, by providing a switched output in response to the passage or approach of an actuating magnet carried by the mechanism. Reed switches are used in a variety of devices, including relays of the electromagnetic and electromechanical type, as well as motion and proximity sensors.
