ABSTRACT:
A MEM's reed switch array is provided having a first switch having a sensitivity causing the first switch to open or close due to a magnetic flux, and a second switch of lesser sensitivity than the first switch causing the second switch to open or close due to a magnetic flux. The first switch can be parallel to the second switch, or the first switch can be proximate to the second switch so that a center line of the first switch is coaxial to a center line of the second switch. Further, a security device for residential and/or commercial use is provided, having a magnet housing having a magnet, a switch housing having a MEM's reed switch array with a first switch and a second switch, and a gap between the magnet housing and the switch housing.
