GRI N150-T-W 1/2" Switch Set, Standard Gap of up to 1", Terminal Connection, Closed Loop, White

Deliver reliable perimeter protection with the George Risk Industries N150-T-W magnetic contact — designed for fast, professional installations in security, surveillance, and monitoring systems. This recessed 1/2" switch set uses rare-earth magnets and press-to-fit contacts to hold a low-profile position while providing consistent actuation. The N150-T-W features a standard gap of up to 1", terminal connections for straightforward wiring, and closed-loop contact functionality to support tamper-resistant alarm and access control circuits. Nickel plating helps prevent chipping and corrosion, extending life in high-traffic doors and windows. Its hybrid recessed mount saves time on new installs and retrofits, and it pairs with the MM-600 when a wider gap is required. Ideal for installers, integrators, and facility managers who need dependable, discreet detection hardware that reduces labor and callbacks.
