Allen-Bradley 800T-QBH2GA2Y Momentary Push Button

Allen-Bradley 800T-QBH2GA2Y is a 30 mm, panel-mount momentary push button from the 800T family, designed for illuminated operator inputs in demanding industrial environments. The QBH2 head variant carries a GA2Y code that identifies green LED illumination and two normally open contacts, enabling two independent input signals from a single actuator. This device is rated for full-voltage operation from 12 to 130 V AC/DC and includes built-in LED illumination for status indication in panels where ambient light is low. Typical applications include start/stop signaling, machine-control panels, conveyor and packaging lines, and other PLC-driven controls where a compact, illuminated momentary button is required.
