Allen-Bradley 800T-B1A Push Button Extended Head

Allen-Bradley 800T-B1A is a 30 mm, momentary push button with an extended head in green and a non-illuminated actuator, designed for panel-mount control in industrial machinery. It offers a dual-contact configuration: 1 normally open (NO) and 1 normally closed (NC), enabling two independent circuits to be operated from a single push. The extended head provides improved reach and visibility in compact control panels, and this head is part of Rockwell Automation’s 800T family, intended to be used with compatible 800T contact blocks to form a complete push-button station for start/stop or interlock-type functions. This combination is commonly used in configurations where a green start or go signaling input is required alongside a second sensing or interlock signal, all within a compact 30 mm footprint.
