Allen-Bradley 800MB-CPA16 Pushbutton

Allen-Bradley 800MB-CPA16 is a 22 mm square pushbutton operator from the 800MB family designed for panel mounting with a flush head that sits level with the enclosure surface. The CPA16 designation places it among the common 22 mm pushbutton options in this line, which includes multiple head configurations and illumination variants, such as pilot-light versions like 800MB-CPA16AD1. In typical industrial-control applications, this pushbutton serves as a control input on machine panels or control stations, and some listings describe CPA16 configurations as momentary-contact devices (with examples noting 120 V operation). The 800MB family is widely used for compact, reliable start/stop and other input functions in automation panels, where a small, rugged 22 mm button is preferred for dense layouts and easy operator access.
