Abstract
An alarm system sensor () monitoring movement of an object (D) and placing the system into alarm when the object moves more than a predetermined distance from a predetermined position. First and second reed switches () are located in a predetermined orientation relative to each other and in tandem to the object. Bias magnets () are used with the reed switches. A magnet () is movable with the object and produces a force simultaneously sensed by both reed switches. This force maintains both reed switches in a state keeping the alarm system in a non-alarm condition so long as the object substantially remains in its predetermined position. The object, when it moves, moves toward one of the reed switches and away from the other reed switch. Movement of the object more than the predetermined distance results in the force sensed by one of the reed switches increasing and the force sensed by the other reed switch decreasing. Either change in sensed force activates the appropriate reed switch causing the alarm system to go into alarm.
