Blue Sea 7929 Contura II Switch SPST Black - OFF-ON

The Blue Sea 7929 Contura II Switch SPST Black - OFF-ON is a marine-grade electrical switch engineered for serious boaters and anglers who demand reliability in harsh saltwater environments. This single-pole, single-throw toggle switch controls simple ON-OFF circuits throughout your vessel—from bilge pumps and cabin lighting to navigation systems and auxiliary equipment. Built by Blue Sea Systems, a leader in marine electrical safety, this switch is designed to handle the punishment that saltwater, vibration, and extreme temperature swings deliver to even the best-maintained boats.

The Contura II series construction delivers genuine weather resistance where it counts: the switch body resists vibration, mechanical shock, thermoshock cycling, moisture intrusion, and corrosive salt spray—the four forces that quietly fail conventional switches offshore. Its compact footprint (2 x 2 x 4 inches) mounts directly into Blue Sea Systems Contura Water Resistant Panels or dedicated Contura Switch Mounting Panels, creating a unified, professional electrical distribution system that protects against unwanted arc-flash and keeps water out of live terminals. The robust toggle action provides clear tactile feedback and zero ambiguity about circuit status, critical when you're troubleshooting systems in rough conditions or low light.

This switch excels for anglers and cruisers running independent cabin or pump circuits that don't require multi-position switching or indicator lights. Its true marine pedigree makes it the go-to choice for anyone upgrading from automotive-grade switches that corrode and fail within two seasons. Installation is straightforward into existing or new Contura panel systems, and the black finish complements modern helm aesthetics while hiding salt spray residue better than polished alternatives. Whether you're rebuilding an old center console's electrical panel or outfitting a new cruising yacht, this switch delivers years of trouble-free service in salt, sun, and spray.
