Manual Single Phase Electrical Changeover Switch

The Manual Single Phase Changeover Switch is typically available in current ratings ranging from 16A to 100A, with voltage capacity up to 250V AC. It is built with a durable enclosure made of powder-coated metal or fire-retardant thermoplastic, designed for surface or flush mounting. The switch features a rotary or toggle-type operation with clear ON/OFF/CHANGEOVER positions, allowing manual transfer between mains and generator/inverter inputs. Terminals are brass or copper alloy for low resistance and long-term durability. The internal contacts are silver-plated or tinned for improved conductivity and reduced arcing. It includes provisions for earth and neutral connections and is often designed with dual-pole or four-pole mechanisms for safe isolation. These switches are compliant with IS/IEC 60947-3 standards and ensure mechanical endurance for up to 10,000 operations. Manual changeover switches are simple to operate, maintenance-free, and cost-effective for managing backup power in single-phase installations
