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.
Reed switches come in two main varieties called normally open (normally switched off) and normally closed (normally switched on). The key to understanding how they work is to realize that they don't just work as an electrical bridge but as a magnetic one as well: magnetism flows through them as well as electricity.

Where simple reed switches often use permanent magnets, the magnetic field in a reed relay switch is generated on demand by pushing current through a coil surrounding the switch. Reed relays are often used in setups that require the actuation of multiple switches simultaneously (or in sequence).
A magnetic reed switch is inherently immune to mechanical wear. A unique characteristic of magnetic reed sensors, or switches, is their capability to support high-speed switching applications without mechanical wear.
Magnetic/reed switches are commonly used in various applications, including security systems, proximity sensing, door and window sensors, and flow meters, where the presence or movement of a magnet needs to be detected reliably and with low power consumption.
