Blue Sea 8421 - 5 Position Contura Switch Panel w/Dual USB Chargers - 12/24V DC - White

The Blue Sea 8421 5 Position Contura Switch Panel with Dual USB Chargers is a marine-grade electrical control system designed for 12/24V DC boat installations, combining five independent switch positions with integrated dual USB charging capability. Built for open-cockpit and flybridge applications, this panel consolidates essential switchgear and device charging into a single watertight assembly, eliminating the need for separate chargers and reducing cockpit clutter on fishing boats and cruising vessels.

The dual USB chargers are rated at 4.8A combined output and incorporate intelligent device recognition to optimize charge rates across different smartphones, tablets, and marine electronics. The panel accommodates both 12-volt and 24-volt DC systems, making it compatible with a wide range of boat electrical architectures. A watertight mounting gasket protects internal contacts from salt spray and moisture intrusion—critical for offshore environments where corrosion can compromise electrical reliability. ON-indicating LEDs embedded in each switch position provide visual confirmation of circuit status, eliminating guesswork when managing multiple systems in low-light conditions or heavy seas.

This panel suits weekend anglers managing basic electrical loads (navigation lights, bilge pumps, fish finders) as well as serious offshore fishermen running multiple systems simultaneously (autopilot, radar, LED spreader lights, battery chargers). The modular five-position design allows each switch to control different circuits independently, providing flexibility in system architecture. Mounted in a white powder-coated housing sized at 7 x 3 inches (12 inches overall with switch stems), the panel fits standard console spaces on center consoles, flybridges, and enclosed cabins without requiring custom fabrication.

Blue Sea Systems manufactures marine electrical components to industrial standards, and the 8421 reflects this build philosophy—stainless fasteners, sealed terminals, and quality gasket materials extend service life in harsh saltwater conditions. When choosing a switch panel for systems integration, verified compatibility with your boat's voltage architecture and total amperage requirements is essential; this dual-voltage design eliminates voltage guesswork for many modern vessels.
