Reed Switch And Magnet Door Sensor Pair

A matched pair of surface-mount housings for a DIY door or window sensor. The switch block has a blind 4.5 mm tunnel for a glass reed switch, with the leads coming out one end. The magnet block has a 22 x 10.5 x 3.5 mm pocket underneath, so the magnet is held against the door. Both are 52 x 14 mm with M4 / #8 screw ears at 42 mm centres, and they print as one piece joined by two snap-off tabs.
