Allen-Bradley 800T-A2A Pushbutton Flush Head Unit

The Allen-Bradley 800T-A2A is a 30.5 mm flush-head, momentary pushbutton in black for panel mounting in industrial control panels. This non-illuminated device delivers a 1NO-1NC contact configuration and includes a 1NO-1NC contact block, enabling a single actuation to energize one circuit while leaving the other open in momentary fashion. The flush-head profile keeps the actuator recessed for a low-profile interface and supports dense panel layouts common with 30.5 mm pushbuttons. It is well suited for basic start/stop signaling and local operator input on machinery and process equipment, and is frequently used in ladder logic circuits where a simple NO/NC signal is required without illumination. As part of the 800T family, the A2A variant provides compact, non-illuminated pushbutton control suitable for applications where illumination is unnecessary.
