Schneider Electric 9001KS88B Push Button Switch

Schneider Electric's Harmony 9001KS88B is a 30 mm panel-mount, non-illuminated selector switch head (Type K) with four fixed positions and a black knob. The metal head is designed for durability in harsh environments, and it supports automatic self-grounding operators without additional wiring, simplifying enclosure wiring. This four-position selector is intended for use with compatible Schneider Electric 9001K-series bodies and is commonly deployed in industrial control panels to select machine modes or control sequences, with a stay-put/manual-return action that holds each position until changed. Distributor listings specify an IP66-rated seal for this model, helping protect the internals from dust and water ingress in demanding applications. The compact, 30 mm footprint and robust construction make the 9001KS88B a reliable choice for applications requiring a rugged, non-illuminated control selector with four discrete states.
