Allen-Bradley 800MR-16HA2BRA Selector Switch Maintained

Allen-Bradley 800MR-16HA2BRA is a two-position selector switch from Rockwell Automation’s 800MR family, designed for panel-mounted control inputs in industrial machinery. It uses a red knob and provides a maintained, non-illuminated actuator, staying in the selected position until rotated to the other state. The switch offers two discrete operator positions, typically labeled X and O, with no built-in lamp or transformer in this model, making it a purely mechanical input suitable for wiring into external control circuits. As part of the 800MR line, it is intended to pair with standard 800MR accessories and mounting hardware for panel installations. This device is commonly used in control panels and switch enclosures to provide operator control over equipment where a simple on/off or mode-selection input is required, and it supports Rockwell’s mounting, bezel, and termination options to fit your enclosure and wiring scheme. Verify the exact mating hardware and ensure correct wiring in accordance with your control schematic; the 800MR-16HA2BRA variant denotes a 2-position, maintained configuration with a red knob.
