They are bigger than they look!
OK I bought a new PVC door and wanted to make the alarm wiring as discreet as possible. In the past I used Maplin who had a small magnet and reed switch but they are stoping so sourced this to fit inside the frame of the door.I was taken aback at the size of these needs a 18mm hole which meant I needed to buy a drill bit (£6 extra). After fully surveying the door it was only possible to put the magnet on the top of the door frame (metal bar runs down length of door). Once I drilled the holes to align the magnet and reed ask that was necessary was to drill hole on frame to connect to existing wiring. You will most likely need additional cable to connect to existing wiring. So lesson learned is to get door fitters to prefit magnet and reed prior to installation which will allow you to totally hide the cable inside frame. Still they are in now and functioning well so given 4 stars for that reason. Not sure why there are 5 terminals only 2(silver headed screws) are active.
