Allen-Bradley 800H-DR2JD1 Pushbutton Mushroom Head

The Allen-Bradley 800H-DR2JD1 pushbutton is a black jumbo mushroom head operator from Rockwell Automation’s 800H family, also listed as WL57-1. This 30 mm class pushbutton is designed for panel mounting in industrial control environments, delivering a clearly visible actuation point for manual machine operation. The jumbo mushroom head provides a prominent, easy-to-find target for operators and supports reliable actuation in demanding conditions, including use with work gloves. The 800H family is built around rugged, interchangeable operator modules that fit standard mounting cutouts and mounting hardware, enabling straightforward replacement and configuration on control panels. The DR2JD1 designation identifies this specific jumbo head style and color combination, so it pairs with compatible 800H frames and contact configurations to implement a wide range of control functions, from simple start/stop to other operator inputs as part of a broader control scheme. In typical installations, this pushbutton serves as the primary human-machine interface for initiating machine cycles or activating safety circuits where a high-visibility, tactilely distinct control is required.
