Schmersal 101164775 Selector Switch NWS21.1WS

Schmersal NWS21.1WS front-element selector switch, Art. No. 101164775, is a compact 22 mm front-diameter control device designed for two-position, maintained operation. The white front element (WS variant) with a long handle provides a robust, hygienic-ready interface for panel-mounted control in demanding environments. As part of Schmersal’s NWS family, this front element forms the visible portion of a selector switch used to select between two operating states in industrial automation—ideal for start/stop, mode selection, or safety-position choices in machinery. The WS variant is specified for washdown-ready applications, delivering a seal and build suited to environments where regular cleaning is required; it is designed to be paired with compatible Schmersal actuators and housings to complete the complete selector switch assembly. Typical applications include food and beverage processing, pharmaceutical equipment, and packaging lines, where cleanability and reliable actuation are essential. The 101164775 front element supports two maintained positions and integrates with standard 22 mm mounting systems for quick replacement in existing control panels, making it a direct-fit component for upgrading or replacing worn front elements in NWS-based selector switches.
