Dry reed switch

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.
