Reed switches actuated by magnets are commonly used in mechanical systems as proximity sensors. Examples are door and window sensors in burglar alarm systems and tamperproofing methods. Reed switches have been used in laptops to put the laptop into sleep/hibernation mode when the lid is closed. See more The reed switch is an electromechanical switch operated by an applied magnetic field. It was invented in 1922 by professor Valentin Kovalenkov at Leningrad Electrotechnical University, and later evolved at See more Reed relays One or more reed switches inside an electromagnetic coil constitute a reed relay. Reed relays are used when operating currents … See more • List of sensors See more • Glossary of Commonly Used Terms Relating to Reed Switch Products • FAQ about Reed Switches See more The most common type of reed switch contains a pair of magnetizable, flexible, metal reeds whose end portions are separated by a small gap when the switch is open. The reeds … See more The mechanical motion of the reeds is below the fatigue limit of the materials, so the reeds do not break due to fatigue.
