SONOFF D1-1 (Wire Splicing Connectors)

These lever wire splicing connectors provide a safer, faster, and more reliable alternative to traditional wire nuts and electrical tape. Built with high-quality PC insulating material, they offer excellent resistance to corrosion, heat, aging, and electrical leakage, ensuring long service life and dependable performance in both residential and professional electrical installations.

Each connector features independent internal shrapnel springs, allowing every wire to be clamped separately. This structure improves safety, prevents wire interference, and ensures stable conductivity, making these connectors significantly safer and more efficient than conventional twist-on connectors.

Designed for convenience, the connectors are fully reusable. Simply lift the lever, remove or replace the wire, and close the lever again; no cutting, re-taping, or rewiring required. Multiple connectors can also be combined into wiring groups to handle more complex connection needs.
