Датчик магнитный дверной Magnetic contact switch [door sensor]

This sensor is essentially a reed switch, encased in an ABS plastic shell. Normally the reed is "open" (no connection between the two wires). The other half is a magnet. When the magnet is less than 13mm (0.5") away, the reed switch closes. They"re often used to detect when a door or drawer is open, which is why they have mounting tabs and screws. But these also have a sticky-foam-tape back so you can also place them in locations you cant attach with screws.
