GRI DS-01T-BW/2.2K Short Roller Ball Brown with 2.2K Resistor

Optimized for dependable intrusion detection and access monitoring, the George Risk Industries GRI DS-01T-BW/2.2K short roller ball plunger switch delivers reliable, repeatable actuation in security and surveillance applications. The 360° ball access provides ultra-smooth plunger travel for longer life and fewer false trips, while the shortened body eliminates the need for a deep mounting hole — speeding installation in tight frames and enclosures. With a total travel of .200" and a pre-travel of .080" ± .030", installers can count on precise, predictable switching behavior. The screw-down flanged collar provides positive retention and consistent positioning, and hermetic sealing plus plated contacts resist sticking or freezing in challenging environments. Factory-installed 2.2K EOL resistor simplifies wiring to alarm control panels; standard 12" 22AWG leads or optional screw terminals and cable types make system integration straightforward. Ideal for door/window sensors, perimeter monitoring, and other security or surveillance systems, this plunger switch is built to perform.
