Allen-Bradley 800T-KA1B Momentary Pushbutton Switch

Allen-Bradley 800T-KA1B is a 30 mm panel-mount momentary pushbutton switch in Rockwell Automation's 800T series. The green operator signals a momentary action and is designed to operate with the standard 800T contact blocks, such as 800T-XA1, which provides a single normally open contact path for control circuits. Rated for up to 600 V AC and up to 10 A, it suits industrial control wiring and machine panels where a compact, robust pushbutton is required. The 30 mm cutout size aligns with the common mounting standard used by 800T devices, ensuring straightforward replacement or upgrade within existing installations. As part of the 800T family, the KA1B option represents a specific operator configuration that maintains compatibility with Rockwell Automation's catalog, simplifying specification and ordering for panel builders and maintenance teams. In practical use, it serves as a momentary input in automation sequences, frequently interfaced with PLCs or relays to initiate a function or signal a control action when pressed.
