Magnetic door / window switches

These magnetic door switch sensors are already seen, if not - then in old movies for sure where they were used as anti-theft devices, ie. alarm systems. In fact, it is a magnet and the reed switch inside a pair. When they are close to each other (recommended 13mm or less), reed switch closes. Connect it to Croduino / Arduino as an ordinary switch use the detection of open doors, windows, drawers, cupboards etc.
