Allen-Bradley 800H-JR2 Maintained Selector Switch

Allen-Bradley 800H-JR2 Maintained Selector Switch is a non-illuminated, 30.5 mm (about 1.20 in) diameter panel-mounted control switch from Rockwell Automation’s 800H family. The JR2 variant is a 3-position, maintained operator with a standard knob and KB7 mounting cam, designed for manual circuit selection in industrial control panels. It fits standard 30.5 mm cutouts and provides a maintained action across its three positions, making it suitable for functions such as start/stop or mode selection in conveyors, pumps, and other equipment. This 800H unit is built for use in rugged environments and is commonly specified for control panels where a simple, tactile selector is required in non-illuminated applications. Applications include machine control panels, process line control, and safety-related interlock or mode-selection tasks where reliable, manually operated switching is needed without built-in lighting.
