Allen-Bradley 800T-QB24A Pushbutton

Allen-Bradley 800T-QB24A is a 30 mm illuminated momentary pushbutton from the 800T family, designed for panel-mount control stations in industrial environments. It features an extended head without guard and an amber lens, and operates on 24 V AC/DC with an incandescent lamp for visible indication. The unit provides a 1-N.O./1-N.C. contact configuration, enabling straightforward signaling for start/stop or interlock logic. Built to Type 4/13 standards, it is suitable for rugged panel installations where a compact, field-replaceable pushbutton is required. This QB24A variant fits standard 30 mm cutouts and aligns with compatible 800T contact blocks, such as the XA family, to complete the circuit wiring. The 800T-QB24A uses momentary action, returning to its rest position when released, making it ideal for momentary input in automation sequences, control panels, conveyors, and machine interfaces where a clearly visible amber indication supports operator awareness.
