SZW26/LW2620/07.4 4P 20A Cam Changeover Switch — compact, reliable manual selector for multicircuit control Why choose this switch Provides positive, indexed switching across up to eight positions (0–7) for clear, repeatable circuit selection. Fourpole (4P) design switches four circuits simultaneously, simplifying multiphase or multicircuit control tasks. Rated for 20A per pole for secure handling of moderate current loads. Compact panel mounting fits a standard 48 x 48 mm panel cutout for spaceconscious installations. Sixteen screw terminals provide solid, lowresistance connections and straightforward wiring. Key attributes Model: SZW26/LW2620/07.4 Pole count: 4P (four poles switched together) Current rating: 20A Positions: 0–7 (8 positions) Panel size/cutout: 48 x 48 mm Terminals: 16 screw terminals Type: Cam changeover (positive mechanical switching between positions) How this solves problems Replaces multiple separate switches or complex wiring by switching four circuits at once, reducing panel clutter and wiring errors. Positive cam action ensures reliable contact engagement and repeatable position indexing, reducing accidental misselection. Secure screw terminals lower the risk of loose connections under vibration, improving longterm reliability. Typical applications Control panels and distribution boards where multiple circuits or phases must be selected or routed manually. Manual changeover tasks such as switching between sources or selecting different output circuits in test benches and production equipment. Industrial machinery control where compact, repeatable multiposition selection is required. Installation and use notes Designed for panel mounting with a 48 x 48 mm cutout; verify panel thickness and mounting hardware compatibility before installation. Wire to the 16 screw terminals using appropriately sized conductors for 20A operation and secure each terminal to the recommended torque for reliable contact. Use the indexed positions (0–7) for clear, repeatable selection; the cam mechanism provides tactile feedback on each step. Benefits at a glance Compact size for tight panels Fourpole switching for synchronized multicircuit control Eight selectable positions for flexible configuration Robust screw terminals for secure wiring Clear model designation for easy replacement and inventory (SZW26/LW2620/07.4) Ordering information Specify model SZW26/LW2620/07.4 and confirm required panel cutout and mounting orientation when ordering or replacing components. This cam changeover switch is suited for applications that require reliable, repeatable multipole selection in a compact 48 x 48 mm panel footprint.
