Blue Sea 8521 - 5 Position Contura Switch Panel w/Dual USB Chargers - 12/24V DC - Black

The Blue Sea 8521 5-Position Contura Switch Panel with Dual USB Chargers is a marine-grade electrical control hub designed for 12/24V DC systems. Built specifically for open-cockpit and flybridge applications, this switch panel consolidates multiple boat functions into a single weatherproof unit while delivering practical charging capability where it's needed most—right at the helm.

The panel features five independent Contura-style switch positions for controlling pumps, lighting, blowers, and other 12/24V DC loads commonly found on center console, sport fishing, and cruising vessels. The integrated dual USB charging system delivers 4.8A output at either 12V or 24V and includes intelligent device recognition technology that automatically optimizes charge rates for smartphones, tablets, and navigation electronics—eliminating the guesswork of manual voltage selection. Individual ON-indicating LEDs embedded in each switch position provide visual feedback in daylight or after dark, critical for verifying circuit status during operation. A watertight mounting gasket seals the panel against salt spray and washdown conditions typical of marine environments.

This control panel suits offshore anglers, weekend cruisers, and commercial operators who need reliable switching without installing multiple separate components. The dual USB ports eliminate the need for aftermarket 12V or 24V charge adapters, addressing a persistent pain point on boats where power management is tight. Black anodized construction resists corrosion in salt air and resists UV fading over years of sun exposure.

Blue Sea Systems is the OEM choice for marine electrical components on production vessels and custom builds, known for engineering durability into systems rated for extended saltwater service. The 8521 integrates into existing Blue Sea modular paneling systems, allowing configuration flexibility as boat systems expand or upgrade.
