Allen-Bradley 800T-QT24R Pushbutton Pilot Light

Allen-Bradley 800T-QT24R is a 30.5 mm pushbutton with an integrated red incandescent pilot light, designed for 24 V AC/DC operation. The QT suffix denotes Push-To-Test, providing a momentary test action for the indicator circuit. This model features a Type 4/13 pilot light housing and includes a single normally open and a single normally closed auxiliary contact (1 NO-1 NC) for signaling in control circuitry. The red lens ensures high visibility in industrial environments, and the full-voltage rating means it operates directly from a 24 V supply without an external resistor. It is compatible with standard 30.5 mm panel cutouts and is part of the 800T family of Allen-Bradley pilot devices, commonly used on control panels for machine status indication and interlock signaling. When wired, the pushbutton serves as both the operator control and a signaling device, with the push-to-test function enabling quick verification of the lamp and contacts.
