The SZW26/LW2620 is a 1pole panel mounted selector switch with a threeposition ONOFFON configuration. It features a manual cam latching action that securely holds the switch in the selected position until deliberately changed. With a 64 mm panel size and four terminals across three wiring lines, it offers flexible wiring options for control panels and equipment. Key benefits Clear threeposition control: ONOFFON positions provide both two selectable outputs and a central off, delivering straightforward, intentional operation. Latching cam mechanism: The manual cam latching design ensures the switch remains in the chosen position without continuous actuation, improving reliability and safety in operation. Flexible wiring options: Four terminals across three lines enable versatile wiring to suit multiple circuit configurations within a single device. Robust electrical rating: Rated up to 660V and 20A, suitable for control circuits in industrial environments. Panel mounting suitability: Designed for a 64 mm panel cutout, enabling straightforward integration into standard control panels. Key attributes Functionality: 1 Pole, 3 Positions (ONOFFON); manual cam with latching action; 4 terminals; 3 lines. Compatibility: Panel mount type compatible with 64 mm panel cutouts; suitable for use in control panels and equipment requiring a threeposition selector switch. Size: 64 mm panel cutout compatible. Performance: Electrical rating of up to 660V and 20A, appropriate for mediumduty control circuits. Construction notes: Material details are not specified in the listing; use within the rated voltage and current limits and follow standard wiring practices. Model/Brand alignment: SZW26/LW2620 selector switch, matching the described specifications and features. Applications and use cases Multiline control circuits: Use the ON positions to connect a common line to one of two outputs, with the OFF position in the center to safely disable the circuit during maintenance. Machinery control panels: Implement as a selector to switch between two operating modes or feeds in a single control input, reducing panel clutter. Power routing in equipment: Route power to alternate subsystems (for example, two different drives or circuits) with a clear, nonambiguous OFF state for safety during setup and service. Notes Ensure a proper panel preparation with a 64 mm cutout for correct fit and secure mounting. Verify wiring to match the 3line, 4terminal configuration and adhere to the 660V/20A rating for safe operation. If environmental conditions exceed standard indoor usage, confirm suitability and any required protective measures per applicable standards.
