Blue Sea 8285 Water Resistant Contura III Switch - Black

The Blue Sea 8285 Water Resistant Contura III Switch in Black is a single-pole, double-throw marine-grade electrical switch engineered for harsh saltwater and moisture-laden environments. Built to withstand the corrosive conditions found aboard vessels of all sizes, this switch delivers reliable on-off control where standard switches fail, making it essential equipment for serious boaters and commercial marine operators.

This Contura III switch is rated for vibration, shock, thermoshock, moisture, and salt spray resistance—specifications that matter on the water where temperature swings, constant motion, and salt-air corrosion destroy ordinary electrical components. The double-throw configuration (ON-OFF-ON momentary action) allows you to control systems with center-off capability, ideal for applications requiring manual reset or dual-direction control. The water-resistant design means no coating degradation or internal corrosion even after months of exposure to spray and humid air, a critical advantage over switches rated only for fresh water or protected environments.

Weekend fishermen installing a new bilge pump, navigational lighting, or cabin fan will appreciate the durability and long service life. Commercial operators, yacht owners, and offshore anglers depend on Blue Sea Systems switches for mission-critical applications where electrical failure isn't an option. The compact 3 × 2 × 5-inch footprint and lightweight 0.1 lb design integrate easily into tight panel spaces without adding weight to your vessel. Whether upgrading aging marine electrical systems or building new installations, the 8285 sets the standard for saltwater reliability.
