Allen-Bradley 800MB-CA9 Illuminated Pushbutton Switch

The Allen-Bradley 800MB-CA9A illuminated pushbutton switch is a 800MB family momentary contact pushbutton unit intended for rugged industrial control panels, featuring a back-lit indicator for visibility in low light. It provides 1 normally open and 1 normally closed circuit, and it uses stab terminals for wiring, making it suitable for compact control inputs or status indication in machine control or panel assemblies. This flush-head, back-lighted pushbutton is listed under Rockwell Automation’s 800MB catalog and is designed to be integrated with other 800MB components for discrete control functions. Note that Rockwell’s official documentation indicates the back-lit variants in the 800MB series, including CA9A, have been discontinued as of June 5, 2024. When selecting this part, verify compatibility with your control circuit and panel mounting, and consider alternatives in the 800MB line if illumination or availability is a concern.
