Schneider Electric 9999SP12R U Selector Switch

Schneider Electric’s Square D 9999SP12R-U is a pilot-light kit designed to accompany Square D’s 9999-series selector switches used in NEMA motor-control circuits. Marketed as a contactor+starter pilot light kit, this model adds illuminated status indication to the associated switch assembly, enabling quick visibility of energized conditions inside control panels. It sits within the 9999 selector-switch family and is identified in distributor catalogs as 9999SP12R-U (with related references such as 9999SP-12R-U appearing in materials from Square D/Schneider Electric). The kit is commonly listed as new surplus by various suppliers and is sold under the Square D/Schneider Electric brand, reflecting its role as an accessory for 9999-series control equipment. By providing a compact, integrated indicator, the 9999SP12R-U helps streamline panel layouts and reduce the need for separate pilot indicators in motor-control installations.
