Allen-Bradley 800T-A2A Pushbutton 1NO 1NC Momentary

Allen-Bradley 800T-A2A Pushbutton is a 30.5 mm flush-head, non-illuminated momentary operator in black, designed for panel mounting in demanding industrial environments. It provides a dual-form contact block: 1 normally open (NO) and 1 normally closed (NC), enabling simple start/stop signaling, interlocking, and control logic within a compact footprint. As part of the 800T family, the A2A variant is compatible with standard 800T contact blocks (such as 800T-XA1) for straightforward replacement or expansion of a control circuit. The flush-head design sits flush with the panel surface to minimize intrusion and snag risk, while still delivering tactile feedback during actuation. This device is non-illuminated, relying on external lighting for visibility rather than built-in illumination, and its momentary action means the circuit changes only while the button is pressed. With its black actuator styling, it integrates cleanly into a wide range of control panels and operator stations, providing a durable, time-tested input solution for industrial automation applications such as machine start/stop, interlock signaling, and process control in harsh manufacturing environments.
