The SZW26/LW2620 is a 20A threepole rotary cam switch designed for panel mounting. It provides 04 position selection, giving five discrete settings in a compact 64x64 mm panel cutout. Featuring silver transfer contacts, it delivers reliable, lowresistance switching across three separate circuits in a single control device. Key benefits Enables control of three circuits from one control element, simplifying panel layouts and wiring. Five selectable positions (0 through 4) allow off and multiple on configurations for flexible circuit control. 20A current rating supports moderateload switching common in control panels, machines, and equipment. Silver transfer contacts improve conductivity and service life, reducing contact resistance over time. Compact panel footprint (64x64 mm cutout) suits standard control panel designs without excessive panel space. Key attributes Model: SZW26/LW2620 Poles: 3 Current rating: 20 A Positions: 0–4 (five selectable positions) Panel cutout size: 64 x 64 mm Type: Rotary cam switch with silver transfer contacts Mounting: Panelmounted design Function: Rotary switching to control multiple circuits from a single control input Applications and use cases Threephase or multicircuit motor control: switch between different circuit configurations or outputs for a motor or other multiline load. Electrical control panels and power distribution: route power to different subsystems or devices from a single control knob. Laboratory or test bench setups: quickly switch measurement or power feeds to multiple instruments during experiments or demonstrations. Notes The description reflects the model specifications: 20A rating, three poles, 0–4 position range, 64x64 mm panel cutout, silver transfer rotary cam switch. Ensure proper panel mounting, wiring practices, and compliance with local electrical codes when installing.
