Blue Sea 7935 Contura II Switch DPST Black - OFF-(ON)

The Blue Sea 7935 Contura II Switch DPST Black is a professional-grade electrical switch designed for demanding marine environments where reliability is non-negotiable. Built for boaters and water-going professionals who depend on rugged, salt-resistant controls in the harshest conditions, this OFF-(ON) switch delivers the dependability you need when you're miles from the nearest technician. Whether you're powering auxiliary systems, running backup electronics, or controlling critical deck equipment, this Contura II switch integrates seamlessly into modern marine electrical panels.

The 7935 employs a DPST (Double Pole, Single Throw) architecture that simultaneously switches two independent circuits with a single lever action, making it ideal for paired electrical loads or redundant safety circuits. Engineered for the saltwater environment, this switch resists vibration, shock, thermoshock, and corrosive salt spray—critical performance factors when operating offshore or in extended freshwater expeditions where moisture accumulation is constant. The compact 2 x 1 x 3-inch form factor and minimal 0.1 lb weight make it ideal for panel space optimization without sacrificing switch durability or thermal performance.

The Contura II mounts directly into Blue Sea Systems Contura Water Resistant Panels and Contura Switch Mounting Panels, ensuring watertight integration that protects your electrical infrastructure from spray and washdown. Experienced boat owners and marine electricians choose this switch for applications ranging from bilge pump controls to thruster circuits and navigation system backup power. Installation is straightforward with standard panel compatibility, and the black finish resists UV fading while maintaining a professional appearance across fresh and saltwater installations.
