Schneider Electric 9001 TP-21 Pushbutton

Schneider Electric's Square D 9001-TP21 is a pilot-light module designed to plug into a Harmony 9001 pushbutton assembly, delivering an amber/orange indicator at 110–120 V AC with a 50/60 Hz supply for clear status signaling in control panels. This 9001-series component provides illuminated feedback for on/off conditions, machine states, or alarm signaling when used with compatible pushbutton operators in industrial control applications. Manufactured by Schneider Electric (Square D), the 9001-TP21 is expressly identified as a pilot light option for 9001 pushbuttons, enabling visible indication without separate lighting modules and helping maintain compact, reliable control-panel layouts.
