The Schurter SWZ1 (Frontpl) is a front-panel mounted voltage selector switch engineered for flexible voltage input configuration in industrial and commercial electronic systems. This six-stage switch supports series-parallel connection topology, enabling multiple voltage selection patterns from a single compact assembly. Rated for 6.3 A / 250 VAC at 50 Hz (IEC), 10 A / 250 VAC at 60 Hz (UL), and 6.3 A / 250 VAC at 60 Hz (CSA), the SWZ1 delivers reliable switching with minimal contact resistance below 10 mΩ at 20 mV and insulation resistance exceeding 10 MΩ at 500 VDC.
