Allen-Bradley 800T-D9A Pushbutton Mushroom Yellow

The Allen-Bradley 800T-D9A is a 30 mm mushroom-head pushbutton with a yellow actuator, offering momentary action and a 1NO-1NC contact configuration. It is non-illuminated and designed for panel mounting in demanding industrial environments, with a NEMA 4/13 rating for weather and dust resistance when installed in suitable enclosures. The device features two discrete contacts—one normally open and one normally closed—allowing a single actuator to serve multiple circuit functions. The 30 mm diameter and mushroom head provide a compact yet highly visible operator suitable for multi-button control panels. Momentary operation means the button returns to its resting position after being pressed. This pushbutton is intended for use in industrial automation applications where a robust, non-illuminated signaling device is needed for start/stop or interlock-type functions in rugged environments.
