Allen-Bradley 800T-QSTH24G Pilot Light Push To Test

Allen-Bradley 800T-QSTH24G is a compact 18 mm pilot light in the 800T family that combines a green LED indicator with a green cap and a push-to-test (PTT) function for quick lamp verification from the panel face. It operates from 24 V AC/DC and is designed to pair with 800T pilot light components for control and automation assemblies, providing a clear green signal to indicate ready or active status. The LED version delivers bright, low-current illumination from a 24 V supply, making it a reliable visual indicator for panel indicators and control circuits. Typical applications include machine automation panels, control stations, interlocks, and equipment signaling where a dependable green status indicator is needed, with the convenience of front-face lamp testing to simplify diagnostics and maintenance.
