Square D 9001KA2N Limit Switch Snap Action NEMA 1

Square D 9001KA2N is a 30 mm contact block designed for use with Square D 9001K/SK modular pushbutton and selector switches, delivering a single normally open (1 NO) circuit in a NEMA 1 enclosure. It features screw-terminal wiring for straightforward field terminations and mounts on the standard 30 mm device footprint, with a 30 mm mounting hole compatible with common pushbutton assemblies. The KA2N variant is rated for 125 VAC and 240 VAC signaling, making it suitable for control panel wiring, interlock logic, and basic signaling in industrial equipment. As part of Schneider Electric’s 9001 Type KA family, this block benefits from Fingersafe construction, supporting safe handling and consistent actuation when paired with compatible 9001K/SK operators. Common applications include panel-mounted control stations, machine control circuits, and signaling configurations where a compact, reliable 1 NO contact block is required to extend functionality of pushbutton or selector switch assemblies.
