GRI 8657 Switch Set, 4532C with HSR634 Reed

Designed to provide dependable, high-current switching for security, surveillance and monitoring applications, the George Risk Industries GRI 8657 switch set (4532C with HSR634 reed) lets installers convert reed contact signals into practical loads. With hermetically sealed solid tungsten contacts and an aluminum case, this magnetic contact is built for long service life in harsh or outdoor environments. The high-temperature leads and availability of 18 AWG wire (gray) allow safe switching of devices in the 3–100 W range—making it ideal for lights, blower motors, pumps, compressors and other field devices commonly used in alarm and access control systems. Because the reed and solid contact are matched for reliable actuation, you get consistent performance in door contacts, perimeter sensors, and remote monitoring points. The compact switch set integrates easily into existing panels and cabling schemes, reducing installation time and maintenance. For security integrators and facilities managers who need a rugged reed-to-contact solution, the GRI 8657 delivers durability and predictable switching.
