Monitor a single sliding door or window on your property with the Seco-Larm 3/8" Rare-Earth Recessed-Mount Magnetic Contact Switch. This recessed magnetic contact sensor fits into the frame of a sliding door or window and sends alerts when the sensor and contact are separated. Made out of high-impact ABS plastic, the switch and magnet have 18-inch wire leads, are designed for closed-loop circuits, and provide an operation gap of half an inch. The contact reed switch is SPST and ruthenium on gold underplating, resulting in higher handling power and longer performance.
