Allen-Bradley 800T-B1A Pushbutton

Allen-Bradley 800T-B1A is a 30.5 mm, non-illuminated momentary pushbutton with an extended green head and a 1NO/1NC contact configuration. It mounts in standard 30 mm panels using a 1-13/64 in (about 30.6 mm) panel cutout, and the extended head provides additional actuation clearance in crowded control panels. This 800T-series operator is designed for rugged industrial environments and is typically used to start/stop circuits or implement simple interlock logic in machine controls. The B1A variant’s non-illuminated design keeps the device simple and durable, while the 1NO/1NC arrangement allows one contact to close on actuation and another to open, enabling versatile wiring schemes in a compact footprint. Compatible with other 800T accessories and standard contact blocks, this pushbutton is a straightforward choice for reliable, maintenance-friendly control stations.
