In any environment where electricity, moisture, and dust coexist, protecting electrical connections is the number one priority for safety and reliability. A high-quality waterproof electrical junction box is the standard solution for shielding vulnerable wiring from the elements. But what if you need more than just a passive enclosure? What if you need to add a heavy-duty, accessible switch directly onto a power cord itself?
This challenge requires a specialized solution. We are proud to present the FILN heavy-duty inline control unit—a product that combines the robust protection of a waterproof electrical junction box with the functionality of a powerful and customizable 30A rocker switch.
This assembly is specifically designed to be installed “inline” on a power cable, giving you the ability to add a safe, convenient, and incredibly durable ON-OFF switch exactly where you need it most.
