Model: SZW26/LW2620/06.3 Type: 3Phase Selector / Transfer Rotary Cam Switch Panel size: fits 64 x 64 mm panel opening Current rating: 20 A Terminals: 12 screw terminals Positions: 7position selector Why choose the SZW26/LW2620/06.3 rotary cam switch Reliable manual switching and source transfer for threephase circuits up to 20 A. Designed for clear position selection and positive mechanical detents. Secure wiring with 12 screw terminals that provide straightforward, robust connections for line and load conductors. Compact, panelmounted design that fits a 64 x 64 mm cutout for easy integration into control panels, distribution boxes, and machinery consoles. Versatile 7position selector allows multiple operating modes or source selections without complex rewiring. Key features and benefits 3phase capability: Simplifies switching of threephase supplies or loads in a single, compact device. 20 A rating: Suitable for many control and distribution applications where switching currents up to 20 amps are required. 12 screw terminals: Makes wiring clear and reliable; terminals accept secure screw connections for each pole and auxiliary lines. 7 positions: Enables several selectable functions such as Off/On, multiple speed or mode selections, or multiple source selections. Panelmount form factor (64 x 64 mm): Standardsized mounting for convenient replacement or installations. Positive cam action: Mechanical detents help prevent misselection and provide a tactile indication of position. Typical applications Generator or source transfer in small commercial or industrial control panels: manually select between utility and backup power or isolate circuits during maintenance. Motor control panels: select operating modes, speeds, or direction settings on threephase motors where a multiposition selector is required. Equipment and machine control: centralize mode selection for production equipment, HVAC control stations, and distribution panels. Installation and use notes Designed for panel mounting; ensure the panel opening is 64 x 64 mm and that mounting hardware and bezel clearance are adequate. Wire to the 12 screw terminals following applicable electrical codes and the wiring diagram provided by system designers; verify conductor sizes and torque settings for 20 A operation. Confirm the required function mapping for the 7 positions before installation (e.g., which positions correspond to Off, Source A, Source B, or specific modes). What this switch solves Reduces the need for multiple singlepole switches by providing coordinated 3phase switching in one unit. Simplifies manual source selection and mode control while maintaining a compact footprint and clear, repeatable operation. Provides a secure, easytowire solution for control panels where reliable manual selection is needed. Compatibility and performance Intended for use where threephase switching up to 20 A is required; compatible with standard control panel mounting practices using a 64 x 64 mm cutout. Use in systems designed for manual selector or transfer operation; match wiring and installation practices to local regulations and system requirements. Ordering information Specify model SZW26/LW2620/06.3 and confirm required panel cutout and wiring layout when or replacing components.
