Schneider Electric 9001KS43B 3 Position Selector Switch

Schneider Electric Harmony 9001KS43B is a 30 mm head for a three-position selector switch, featuring a stay-put (maintained) action with a Cam C detent and a black knob. Designed to mount on panels as part of the Harmony 9001K modular system, this head is intended to be paired with a compatible 9001K base to form a complete selector switch assembly. The head is constructed from metal and uses a standard handle, and it supports three discrete positions defined by the Cam C configuration. For installation, the 30 mm footprint matches standard 30 mm cutouts, and the durable metal construction resists wear in demanding environments. The Cam C detent profile is aligned with the three-position configurations used across the Harmony 9001K family, providing tactile feedback at each position for reliable operation. Common applications include control panels in manufacturing lines, packaging equipment, and automated systems where a three-state selector is required. This head-specific model is part of Schneider Electric's Harmony 9001K lineup, designed to be swapped with other 9001K heads or bases to customize a panel control solution.
