The SZW26/LW2620 is a panelmount rotary turn switch conversion controller designed for voltage and current applications. It features 8 phases, 32 screw terminals, and an 8P ONOFFON panel configuration. With a 64 mm panel diameter and ratings of 660 V and 20 A, this device provides a reliable way to configure and control multiple circuits from a single control point. Key benefits Supports eight phases from a single rotary switch, simplifying multichannel configuration and wiring in control panels. ONOFFON arrangement offers two selectable ON positions with an OFF interval between them for clear, deliberate operation. voltage and current capability (660 V, 20 A) suitable for industrial conversion and control tasks. 32 screw terminals provide ample connections for routing and wiring across eight poles. Compact panel footprint with a 64 mm diameter, enabling integration into standard control panels.
