Allen-Bradley 800HC-QRTH2B Push Button Pilot Light

The Allen-Bradley 800HC-QRTH2B is a 30 mm push-button with a blue LED pilot light designed for 12–130 V AC/DC operation. This Full Voltage 800H device combines a push-to-test action with a blue LED indicator and provides a 1 normally open and 1 normally closed contact set for flexible logic wiring. With its 30 mm standard footprint, the QRTH2B fits typical panel cutouts used in industrial control panels and aligns with other 800H 30 mm pushbuttons in the family. The blue pilot lamp offers immediate visual signaling to operators when the control is energized or a circuit condition is active, helping to distinguish functions in complex panels. Terminals are equipped with finger guards to improve wiring safety during installation and maintenance. The QRTH2B variant is commonly deployed in machine control, start/stop signaling, and indicator applications where a compact, durable pilot-light pushbutton is required and where a single device must provide both actuation and status indication. This specification aligns with the 800H family’s pushbutton/indicator line, delivering reliable operation in automated systems while avoiding the need for separate pilot-light modules.
