Allen-Bradley 800T-QTH24A Illuminated Push Button

Allen-Bradley 800T-QTH24A Illuminated Push Button is a 30 mm modular operator from the 800T family that combines a push-button action with an integrated indicator light for clear status signaling in control panels. The QTH24A variant is designed for 24 V AC/DC operation to power the illumination, making it suitable for panel assemblies and machine interfaces that rely on standard low-voltage signaling. This family follows a modular approach, allowing the push button to be paired with standard 800T contact blocks to achieve practical signaling configurations and easy field wiring. In the 800T lineup, 24 V illuminated options illustrate the range of lamp types and head configurations available while preserving a common 30 mm footprint and mounting interface, with other 24 V variants such as 800T-QSTH24A (LED pilot light), 800T-QB24A (30 mm push button), and 800T-QA24A (amber head) serving as reference points for compatibility and replacement. The 800T family is widely used in industrial control panels to provide reliable operator input combined with visibility, backed by Rockwell Automation’s design approach that emphasizes interchangeability of heads, guards, and contact blocks across the same footprint.
