Allen-Bradley 800S R3SX Three Position Selector Switch

Allen-Bradley 800S-R3SX is a three-position Hand-Off-Auto selector switch housed in a NEMA Type 1 enclosure for indoor panel applications. This 800S family device provides three selectable states—Hand, Off, and Auto—allowing manual actuation, a safe stop state, or automatic operation in process and machine control circuits. The enclosure is designed for standard industrial panel installations, making it well-suited for mounting in control cabinets in manufacturing environments. Rockwell Automation literature explicitly identifies the 800S-R3SX as a Hand-Off-Auto selector switch and notes the HOA configuration, with the catalog number 800S-R3SX accommodating typical 800S accessories and mounting practices. Common uses include motor control sequencing, equipment interlocks, and control-system mode selection where clear state indication and reliable actuation are essential.
