SZW26/LW2620 3Position Rotary Changeover Cam Interruptor / Selector Switch — 56 Terminals, 14 Gears, 20A, 48 x 48 mm Why this switch matters Precise multicircuit control: Three selectable positions let you reliably switch circuits or modes without complex wiring changes. connection capacity: 56 terminals provide extensive wiring flexibility for controlling multiple lines, contacts, and sequences from a single switch body. Robust current handling: Rated for 20A to support heavier loads compared with small panel switches, reducing the need for additional relays or contactors in many applications. Configurable cam action: 14 gears (cam segments) enable customized contact sequences for timed, stepped, or multioutput switching tasks. Key features and specifications Model: SZW26/LW2620 Switch type: Rotary changeover cam interruptor / selector switch Positions: 3 selectable positions Terminals: 56 terminals for complex wiring configurations Gears: 14 gears (cam segments) for configurable contact sequences Current rating: 20A Mounting / size: Designed for 48 x 48 mm panel cutout What this switch delivers Simplifies control panel design by consolidating multiple switching functions in one compact rotary unit. Allows complex switching logic without adding multiple separate switches, saving space and reducing wiring complexity. Provides a dependable mechanical cam mechanism that ensures repeatable switching behavior across cycles. Typical applications Industrial control panels: Use as a mode selector to switch between manual/automatic/maintenance modes while controlling multiple circuits from one selector. Machinery and equipment: Implement stepped sequences or changeover functions for motor direction, speed ranges, or auxiliary systems where multiple contacts must operate together. Power distribution or transfer systems: Use for source selection, transfer between supply lines, or multicircuit isolation requiring a compact, terminalcount selector. Installation and compatibility notes Intended for panel mounting in a 48 x 48 mm cutout. Verify panel thickness and mounting details per your enclosure design. 56 terminals provide flexibility — plan terminal labeling and wiring sequence before installation to reduce setup time. The 14gear cam arrangement can be set up to match required contact sequences; consult wiring diagrams or a qualified electrician for complex configurations. Durability and use Designed for repeated mechanical operation and clear position detents for reliable user feedback. Suitable where compact, capacity selector switching is required. For safety and compliance, ensure the switch is integrated with appropriate fusing, overload protection, and enclosure ratings as required by your application and local regulations.
