Blue Sea 7932 Contura II Switch SPDT Black - (ON)-OFF-ON

The Blue Sea 7932 Contura II Switch SPDT Black with (ON)-OFF-ON action is a marine-grade electrical switch engineered for harsh saltwater and high-vibration environments where reliability is non-negotiable. Designed for bilge pump control and other critical onboard switching applications, this Contura II switch delivers the durability required on fishing boats, cruisers, and offshore vessels operating in corrosive marine conditions.

Built to withstand vibration, shock, thermoshock, moisture, and salt spray—the core challenges of marine electrical systems—this SPDT switch handles maximum amperage of 20A at 12V or 15A at 24V, making it suitable for moderate-load bilge pump circuits and similar marine DC applications. The (ON)-OFF-ON configuration allows independent control of two separate circuits or dual-function operation within a single switch. Operating current draws just 18mA, minimizing parasitic drain on vessel battery banks during idle periods. The switch mounts directly into Blue Sea Systems Contura Water Resistant Panels and Contura Switch Mounting Panels, integrating seamlessly with standardized marine electrical enclosures.

This switch suits weekend anglers upgrading bilge pump control on center consoles, skiffs, and cabin cruisers, as well as serious offshore operators who demand redundancy and fail-safe operation in rough water. The black Contura II actuator provides clear visual feedback and integrates with Blue Sea's modular switch panel ecosystem, allowing customizable control layouts tailored to vessel layout and crew preferences.

Blue Sea Systems is the marine electrical industry standard for safety-certified DC distribution and switching. Contura II switches are found on commercial fishing vessels, naval craft, and high-end production boats where corrosion resistance and long service life directly impact vessel safety and resale value. This switch represents the professional-grade approach to bilge pump switching—no compromise on environmental sealing or electrical performance.
