Allen-Bradley 800S-2SA Start-Stop Push Button Station

Allen-Bradley 800S-2SA Start-Stop Push Button Station is a standard-duty, single-station control device in the 800S family. Housed in a Type 1 enclosure, it combines two momentary-contact pushbuttons for a classic Start/Stop control: Start is normally open (N.O.) and Stop is normally closed (N.C.), enabling a simple Start-Stop circuit in indoor panel environments. The unit is designed for applications such as motor control, conveyors, and general machine start/stop operations where a compact, reliable operator interface is required. In a typical setup, pressing Start energizes the control circuit, while pressing Stop opens the circuit to halt operation; the Start input can be paired with downstream holding circuitry to maintain the run state after release. The 800S-2SA’s two-button configuration supports streamlined panel layouts by consolidating control into a single station, and its momentary contacts align with standard control logic used across industrial automation systems.
