Allen-Bradley 800T-FX D4 Pushbutton

Allen-Bradley 800T-FX D4 Pushbutton is a 30 mm mushroom-head operator from Rockwell Automation’s 800T family, featuring a red cap and a D4 contact block (1-NCLB) in its standard configuration. The FX head designation indicates Push-Pull action, delivering a rugged, panel-mounted control point for industrial environments. Illuminated variants are available, including LED versions that operate from 12 to 130 V AC/DC to provide clear status indication in dim environments. This 800T-FX D4 arrangement is commonly used for simple start/stop and general machine-control circuits, and it supports Rockwell’s modular accessory ecosystem for guards and expanded contact configurations. The combination offers a compact, reliable operator that fits standard 30 mm cutouts and pairs with compatible 800T contact blocks to tailor the electrical function to the application.
