Protect windows without compromise—George Risk Industries' N20RS-12 Series Switch Set with the MM-400 rare earth magnet delivers a low-profile, reliable solution for window security and alarm monitoring. Designed for recessed mount installations, this 0.4" diameter contact magnet sits under 1/8" high, preventing damage to thin vinyl frames while maintaining a consistent standard gap for closed-loop monitoring. The compact rare-earth magnet provides strong holding power in a smaller footprint, enabling discreet installation for residential and commercial surveillance systems.

Installation is fast and flexible: mount recessed with the supplied stainless screws, use the included double-stick tape, or glue into place. Nickel plating offers corrosion resistance for long-term field performance, and the unit is color-matched brown for a discreet appearance on most window frames. Ideal for window sensors, alarm contacts, and broader physical security setups, the N20RS-12 reduces install time and service calls. Available in minimum order quantities of 10 and backed by a lifetime warranty, it’s a reliable choice for security integrators and monitoring professionals.
