The SZW26/LW26160 is a current, singlephase rotary changeover cam switch designed for industrial control panels and heavyduty electrical installations. With a threeposition OnOffOn operation and four terminals, it provides a straightforward way to select between two loads or circuits while offering a dedicated off position for safe servicing. Rated at 160 A and 660 V, it is built to handle demanding applications with reliable mechanical performance. Key benefits current and voltage capability: suitable for switching substantial singlephase loads up to 160 A at up to 660 V. Threeposition changeover: OnOffOn configuration enables operation of two selectable outputs with an integral off position for safe maintenance. Rotary cam actuation: smooth manual operation with repeatable positioning for dependable control. Four terminals: flexible wiring options to connect input and two outputs or to accommodate a control wiring scheme. Singlephase compatibility: designed for common AC mains applications found in industrial environments. Robust control component: intended for panelmounted use in control systems requiring durable, longlife switching. Key attributes Model: SZW26/LW26160 Position: 3position OnOffOn Phase: 1 phase Current rating: 160 A Voltage rating: 660 V Terminals: 4 Type: Rotary changeover cam switch Application: OnOffOn control for singlephase circuits in industrial equipment and control panels Applications and use cases Motor control for singlephase equipment: select between two windings or feeds to enable start/stop with a safe off position between selections, useful for simple motor reversing or choosing between two drive circuits. Dualload switching: power two independent loads from a single switch location, allowing easy selection of which load is energized while keeping the other off. Equipment control in machinery: toggle between two circuit branches (for example heating element A vs heating element B, or two lighting/indicator banks) with a off position for maintenance or safety shutdown. Wiring and installation considerations Fourterminal configuration supports flexible wiring for input and two selectable outputs; connect per the equipment's wiring diagram and applicable electrical standards. Ensure wiring gauge and enclosure protection meet the 160 A at 660 V rating, and install in accordance with local electrical codes. Use a proper mounting arrangement suitable for panel installation and provide secure mechanical mounting to prevent vibrationrelated contact issues. Maintenance and safety Always deenergize the circuit before wiring, servicing, or replacement. Consult applicable safety standards and certifications for your region and application. Inspect connections and the switch mechanism periodically for signs of wear or damage and perform repairs or replacement as needed.
