George Risk Industries 29A-W White Surface-Mount Magnetic Contact Switch Set

Add opening-position monitoring to a door, window, cabinet, or other movable protected surface with a white magnetic contact switch set mounted directly on the surface. The contact and matching magnet change state as the protected opening moves, providing a signal point for a compatible physical-security or alarm circuit. The white housing helps the installed component blend with light-colored frames, trim, and enclosures. Surface mounting places the switch set on the face of the protected opening and its adjacent frame rather than inside a drilled recess. That approach suits retrofits, finished surfaces, metal frames, cabinets, and installations where access for recessed mounting is limited. Installers can position the two set components so they align when the opening is in its normal closed position. George Risk Industries 29A-W is the white surface-mount configuration for visible opening monitoring. Its switch-set format provides the paired components needed to detect separation between the protected surface and its frame. Use it where an alarm or access-control installation needs a discrete status point without changing the construction of the opening. Verify placement, alignment, wiring method, and circuit compatibility against the requirements of the connected control equipment before installation.
