Schneider Electric 9001KS53B Momentary Selector Switch

The Schneider Electric 9001KS53B is a 30 mm diameter, three-position momentary selector switch with spring-return to center from both sides. Part of the Harmony 9001 family, it uses a Type K cam and a black knob on a non-illuminated body, and is rated for up to 600 V. This momentary (MO) configuration supports on-demand actuation ideal for start/stop sequencing, mode selection, or lightweight control logic in panel-mount applications. The compact footprint aligns with standard 30 mm cutouts and is designed to pair with Schneider Electric 9001 heads and accessories for flexible configuration in control panels, instrument enclosures, or machine dashboards. The three-position arrangement enables distinct off/momentary-on signals depending on cam coding, making it suitable for simple control circuits in industrial automation. Typical uses include motor-start sequencing, equipment mode selection, and process-control panels where a quick, tactile selector action is required.
