Spacesaving panel installation: Designed for a 64 x 64 mm panel footprint to fit compact control enclosures and switchboards. Simple wiring and maintenance: Four terminal connections allow direct, logical wiring of incoming and outgoing conductors, simplifying installation and troubleshooting. Key attributes Model: SZW26/LW2620 Type: Selector rotary cam changeover switch Poles: One pole Terminals: Four terminals Panel size: 64 x 64 (panel mounting) Current rating: 20 A Voltage rating: 660 V How it solves common problems Eliminates ambiguous power routing: Makes manual selection or changeover between circuits fast and unambiguous, reducing operator error. Reduces panel clutter: A dedicated 64 x 64 panel footprint simplifies layout planning and keeps control panels compact. Minimizes downtime: Robust electrical ratings and straightforward terminal arrangement speed up installation and service. Compatibility and application notes Suitable for panel mounting in control cabinets, switchboards, and machine operator stations sized for a 64 x 64 mm cutout. Four terminal connections accommodate typical line/load wiring; check wiring diagrams and panel layout for terminal labeling before installation. Designed for use where a onepole selector or changeover function is required; verify control circuit compatibility and safety requirements for your installation. Typical use cases Machine control panel: Manual selection of motor start/stop circuits or selection between local and remote control sources. Power source selection: Changeover between two supply lines or routing for maintenance isolation in industrial distribution panels. Equipment control stations: Operator selector for mode selection, emergency isolation, or alternate circuit routing in factories or workshops. Installation and safety reminders Confirm the panel cutout and mechanical mounting dimensions are compatible with a 64 x 64 mm panel opening. Ensure all wiring is carried out by a qualified electrician and complies with local electrical codes and safety standards. Observe the 20 A and 660 V ratings; do not exceed specified limits to maintain safe operation and long service life. Practical, compact, and engineered for dependable changeover performance, the SZW26/LW2620 selector rotary cam changeover switch is a straightforward solution for circuit selection in industrial and commercial panels.
