GRI 410-G 4" Commercial and Industrial Surface Mount Switch Set, Closed Loop, 1-1/2" Standard Gap

For dependable perimeter detection and access monitoring in commercial and industrial environments, the George Risk Industries GRI 410-G magnetic contact switch set provides a rugged, installer-friendly solution. Designed as a closed-loop, surface-mount switch, the 410-G offers a compact 4-inch profile and a 1-1/2-inch standard gap to suit metal frames, doors, and gates where consistent contact performance is critical. Choose concealed terminals (400) or side terminals (410) for clean installations, or the 410P variant with a 36-inch vinyl-jacketed pigtail for faster wiring to alarm panels and controllers. Constructed from steel and meeting the UL 10C fire rating, this magnetic contact supports continuous security, surveillance and monitoring applications while minimizing service calls. Built-in EOL resistor and diode options simplify circuit design, and private labeling is available for OEM or managed security programs. Backed by a lifetime limited warranty, the GRI 410-G is engineered to deliver long-term value and peace of mind. Add the GRI 410-G to your next access control or intrusion detection project to improve reliability and streamline installation.
