Schneider Electric 9001SKS43 Maintained Selector Switch

Schneider Electric’s Harmony 9001SKS43 is a 30 mm panel‑mount selector switch head, designed for three-position, maintained operation in industrial control panels. This plastic-bodied, non‑illuminated operator is supplied as a head component (without a handle) and is intended to be used with Schneider Electric contact blocks to build common control circuits; for example, when implementing HAND‑OFF‑AUTO configurations, it can be paired with a 9001KA1 contact block behind the 9001KS43/9001SKS43 assembly. The 9001SKS43 family is offered in variants that include a knob and push‑button—such as 9001SKS43BH1 (black knob) and 9001SKS43BH13—providing a convenient operator option while preserving the same three‑position, maintained functionality and 30 mm mounting footprint. Ratings for these 9001SKS43 configurations align with typical Harmony 9001MA assemblies, with a common specification of up to 600 VAC at 10 A when used with compatible contact blocks. This makes the 9001SKS43 suitable for a range of panel‑mount control tasks in equipment like conveyors, packaging lines, and process‑control applications where a reliable, mechanically held position is required for selecting modes or enabling/disabling functions.
