The SZW26/LW2620 is a 5position, 3phase rotary cam switch designed for panel mounting. With a rated insulation voltage Ui of 660 V and a current rating of 20 A, it provides reliable control for threephase circuits in compact control panels. The switch features 12 terminals and a 48x48 mm panel footprint, making it suitable for standard enclosure designs. The positions are labeled 1 through 5, offering flexible configuration options for switching between different circuit states. Key benefits Clear 5position selection for 3phase circuits, enabling quick and reliable mode or speed changes. 12terminal configuration supports organized, multiwire wiring for line and load connections within a single device. Panel mounting with a 48x48 mm footprint fits common control panels and enclosures, simplifying integration. Ui 660 V insulation rating and 20 A current rating provide safe operation for moderate power switching in industrial settings. Durable rotary cam mechanism supports repeated operation in demanding environments while maintaining stable contacts and performance. Key attributes Model: SZW26/LW2620 Type: Rotary cam switch Phases: 3 Positions: 5 (12345) Terminals: 12 Panel cutout footprint: 48 x 48 mm Mounting: Panel mounted Insulation voltage (Ui): 660 V Current rating: 20 A Wiring arrangement: 12 terminals arranged to support multiwire, threephase control Applications and use cases Motor control in compact control panels: Use the 5position switch to select different motor start sequences or operating modes for a small threephase motor. Threephase power routing in distribution panels: Route power to different loads or circuit paths in a controlled, multiposition manner within a single device. Equipment or machine mode selection: Implement predefined configurations for equipment such as conveyors, fans, or pumps, enabling quick changeovers with a single switch. This switch is suitable for industrial automation tasks requiring reliable 3phase switching with multiple wiring terminals, compact panel compatibility, and a robust 5position control option.
