It's pretty simple -- the maganet pulls on a flexible "bar" (strip) and holds it away from a contact point. When you open the door, the magnet is no longer holding the bar-- and it falls back into its natural position... It is the very simplisity of it that make it easy to overcome.. take some of those flat, flexable magnetic sheets-- the would almost fit between the door and the frame... It is fun "science project" for a 10 to 15 year old to set up an "alarm circuit" with a door bell and some magnets, and some magnetic switches (and it can be recyle it to an other project by replacing magnet switches with "tilt" switches-- for a motion detector!)
And now i move from being a fellow AWAD, to being a felonious one!
