Blue Sea 8218 Water Resistant Contura III Switch - Gray

The Blue Sea 8218 Water Resistant Contura III Switch in gray is a marine-grade electrical switch engineered for serious boaters and anglers who demand reliability in harsh saltwater and freshwater environments. Whether you're running electronics at the helm, controlling bilge pumps, or managing cabin power systems, this double-pole, single-throw switch delivers the dependability required for extended time on the water. Built to withstand spray, splash, and moisture exposure, it's a core component for any well-maintained vessel's electrical infrastructure.

The Contura III design features a water-resistant sealed housing that protects internal contacts from corrosion—a critical advantage when saltwater spray and humidity threaten conventional switches. The double-pole configuration allows simultaneous control of two separate circuits, ideal for managing redundant systems or coordinating related electrical loads. Gray anodized finish resists UV degradation and corrosion, ensuring the switch maintains both function and appearance through seasons of exposure. The compact 3 x 2 x 4-inch profile fits easily into tight helm spaces without consuming valuable real estate on your control panel.

Experienced boat owners and tackle anglers rely on Blue Sea Systems switches for their reputation in marine electrical standards and longevity. Installation is straightforward into existing panel cutouts, and the robust build quality means this switch will outlast less durable alternatives found in general-purpose electrical supplies. If you're upgrading aging panels, building out a new center console, or simply replacing corroded switches that have proven unreliable, the Blue Sea 8218 Water Resistant Contura III Switch delivers professional-grade performance at a price that reflects its durability and marine-specific design.
