SZW26/LW2620 20A 660V 1 Pole ON OFF ON Power Supply 3 Gear Mechanical Changeover Selector Cam Switch Why choose this selector cam switch Precise manual control: Provides threeposition switching (ON – OFF – ON) for safe, unambiguous selection between two live circuits or between a live circuit and off. electrical capacity: Rated for up to 20 A and 660 V, suitable for many industrial and commercial power control applications. Reliable mechanical changeover: The 3gear cam mechanism gives positive, repeatable switching action and clear detents for each position. Key features and attributes Model: SZW26/LW2620. Electrical rating: 20 A, 660 V. Pole count: Single pole (1P) — switches one circuit/phase. Positions: ON – OFF – ON (threeposition selector). Mechanism: 3gear mechanical changeover cam provides stable, tactile position selection. Functionality: Manual selector for switching and routing power in control circuits, supply lines, or equipment. Benefits (how it solves problems) Prevents confusion during source selection by providing distinct ON/OFF/ON positions, reducing wiring errors and improving operator safety. Handles moderate current and voltage levels, so it can be used where a simple, sturdy manual changeover is required without complex electronics. Mechanical design reduces risk of accidental switching and provides longterm repeatability for routine operations. Compatibility and performance Designed to work in electrical control and power supply circuits up to the rated 20 A / 660 V. Singlepole design minimizes footprint while controlling one feed or phase at a time. Mechanical cam action yields consistent contact engagement across many cycles for dependable on/off switching. Suggested applications / use cases Power source selection: Manually switch a device between two power sources or two distribution feeds, with an off position between sources. Equipment control and isolation: Use as a local control on machines or panels to isolate a circuit or select an alternate feed during maintenance or testing. Test benches and prototypes: Provide a clear, repeatable method to route power during equipment development or troubleshooting. What to expect during use Positive, tactile switching with clear ON and OFF detents. Straightforward integration into control panels or wiring arrangements that require singlepole manual changeover. Suitable where a robust, mechanical selector is preferred for simplicity, reliability, and operator clarity.
