The SZW26/LW2620 is a 20A ON OFF ON threegears 2 phase 660V AC selflocking manual selected cam switch designed for panel mounting with a 48x48 mm panel size. It provides reliable, multi position control in control panels and machinery, allowing secure and adjustable circuit selection without continuous hand force. Key benefits Three position ON OFF ON operation enables flexible control in a compact form, with an OFF state that safely interrupts power. Self locking mechanism maintains the chosen position without requiring constant manual holding, improving safety and reducing operator effort. current capability of 20A supports moderate load applications and typical control circuits. Voltage rating of 660V AC with 2 phase compatibility suits standard industrial power distribution environments. Compact 48x48 mm panel size fits standard control panel cutouts and enables dense wiring layouts. Robust manual cam switch design provides reliable switching action suitable for industrial use. Key attributes Model: SZW26/LW2620 Switch type: Manual selected cam switch with self locking Gear arrangement: 3gears (ONOFFON) Voltage rating: 660V AC Phase: 2 Phase Current rating: 20A Panel cutout size: 48x48 mm Mounting: Panel mounted Applications and use cases Control panels in industrial machinery where two circuit paths are alternated or selected, with a secure OFF state and a secondary ON path. Machinery and automation systems requiring a compact, self locking cam switch to manage dual power feeds or modes without continuous holding. Motor control or process control panels where reliable threeposition switching is needed to select between operating modes or circuits while maintaining a defined safe state. Notes Aligns with standard panel mounting practices for 48x48 mm devices. Designed for scenarios requiring manual, self locking, three position switching with a 660V AC, 2 phase supply.
