Model LW2620/3 Transfer Switch — 3Positions Rotary Selector Cam Changeover Switch (102, On‑Off‑On, 440V 20A) Why choose this switch Provides a simple, reliable way to switch between two electrical sources with a neutral/off position. The LW2620/3 is a cam changeover rotary selector designed for clear, positive switching in systems rated up to 440V and 20A. Solves the common need for safe manual changeover: choose source 1, turn to off, or select source 2 with a single rotary motion. Reduces wiring complexity and operator error when switching circuits or power sources. Compact, purposebuilt design for panel or control applications where a robust On‑Off‑On selector is required. Key benefits (how it helps) Secure source selection: 102 (On‑Off‑On) layout prevents accidental crossconnection and makes selection intuitive for operators. Durable cam changeover action: designed to provide positive contact switching for reliable operation over repeated cycles. Versatile use: rated for 440V and 20A, fitting many industrial, commercial, and utility switching tasks where a manual transfer or selector is needed. Main features and attributes Model: LW2620/3 Functionality: Transfer switch / cam changeover rotary selector Positions: 3Positions — 102 configuration (On‑Off‑On) Rated electrical capacity: 440V, 20A Operation: Rotary selector for manual source selection Action: Cam changeover mechanism for clear, defined switching Compatibility and performance Compatible with control panels, switchgear, and equipment that accept a manual rotary selector for source selection or circuit routing and that operate within the 440V/20A rating. Provides reliable manual isolation between two sources with an intermediate off position, suitable for repeated switching in operational routines. Typical applications / use cases Generator or backup power selection: Manually transfer loads between primary supply and backup generator with a clear 102 selector. Control and distribution panels: Offer operators a straightforward On‑Off‑On selector to route power or enable specific circuits during maintenance or testing. Machine/tool changeover: Select between two supply lines or control modes in industrial machines where a visible, tactile selector is preferred. Installation and operation notes Use within the stated electrical ratings (440V, 20A). Ensure installation and wiring are performed by a qualified technician according to local regulations. The 102 (On‑Off‑On) arrangement provides an obvious centeroff position for safe interruption before switching to the alternate source.
