SZW26/LW2620 3 Position ON OFF ON Rotary Changeover Cam Switch — 8 Phase, 32 Terminals, 20A, 64X64 Panel A compact, easytoinstall rotary changeover cam switch designed for reliable multicircuit control. The SZW26/LW2620 provides a clear threeposition action (ON — OFF — ON) and extensive wiring options with 32 terminals across 8 phases, making it a practical choice for panels that require flexible switching between two circuits or sources. Key benefits Simple, intuitive switching: threeposition ONOFFON operation lets you alternate between two outputs or sources with a center OFF for isolation. Multicircuit capability: 8phase configuration and 32 terminals support complex wiring requirements without additional components. Panelfriendly size: fits a 64 x 64 mm panel cutout for neat integration into control cabinets and distribution boards. Clear specification for dependable performance: 20A rated switching for typical control and distribution applications. Key attributes Model: SZW26/LW2620 Switching positions: 3 (ON — OFF — ON) Phases/poles: 8phase Terminals: 32 terminals for flexible wiring Current rating: 20A Mounting: 64X64 panel cutout compatibility Type: Rotary changeover cam switch Functionality and compatibility Designed to switch or change over multiple circuits in a single compact device. The center OFF position provides a safe, visible isolation point between two selectable ON positions. 32 terminal arrangement allows grouped or independent connections for each phase, simplifying wiring in multipole applications. Intended for panel mounting where a 64 x 64 mm cutout is standard. Typical applications Control and distribution panels: Select between two power sources or two sets of outputs in industrial or commercial switchboards. Equipment changeover: Alternate feeds for motors, pumps, or machinery that need a selectable source with a centeroff isolation. Multicircuit control: Use in machine control panels or automation cabinets where multiple poles must be switched simultaneously. Installation and use notes Fits standard 64 x 64 mm panel cutouts for straightforward mounting. Ensure wiring follows the 32terminal layout and local electrical codes; do not exceed the 20A rating. Use the center OFF for safe isolation before maintenance or reconfiguration. The SZW26/LW2620 delivers straightforward ONOFFON changeover capability with extensive terminal options and panelfriendly sizing to meet multicircuit switching needs in control and distribution environments.
