Allen-Bradley 800MR-HH2BB 2-Position Maintained Selector Switch

Allen-Bradley 800MR-HH2BB is a rugged, round oil-tight two-position selector switch with a black knob, designed for heavy-duty industrial control panels and applications where a clearly defined, manually selected state must be maintained across cycles in harsh environments. This non-illuminated 800MR unit provides two maintained positions for on/off or mode-selection tasks and uses an A/B contact arrangement that switches two circuit paths, with stab-terminal wiring options that enable secure, vibration-resistant terminations on crowded panels. The HH2BB suffix specifies the black-knob option within the 2-position maintained family, and the 800MR line is built for durability with round oil-tight construction that resists dust, oil, and moisture ingress in production facilities. Common uses include manual/auto selection, start/stop control, and simple signal routing on conveyors, presses, or packaging lines, where a robust, non-illuminated switch with a fixed state is essential for reliable operation and clear operator feedback.
