Schneider Electric Square D 9001-KQ18 is a 30 mm pushbutton assembly from the Harmony 9001 family that pairs a momentary pushbutton with a maintained selector switch action. In this model, the pushbutton portion is momentary while the selector function remains maintained, enabling a compact two-function control for start/stop or mode selection in control panels. Designed for industrial panel installations requiring a single, space-efficient operator, the 9001-KQ18 integrates with standard 30 mm mounting practices used across Square D's 9001 line.
