Blue Sea 7933 Contura II Switch SPDT Black - (ON)-OFF-(ON)

The Blue Sea 7933 Contura II Switch SPDT Black in (ON)-OFF-(ON) configuration is purpose-built for marine electrical systems where dual-function switching is essential. Whether you're managing navigation lights, bilge pumps, or auxiliary power circuits, this robust switch delivers reliable control in the harsh saltwater environment. Designed by Blue Sea Systems—the trusted standard in marine electrical architecture—this toggle switch handles the demanding conditions of open water where moisture, vibration, and thermal shock are constants.

Built with vibration, shock, thermoshock, moisture, and salt spray resistance engineered into its core construction, the Contura II delivers consistent performance through years of challenging conditions. The (ON)-OFF-(ON) SPDT (Single Pole Double Throw) action allows independent control of two separate circuits—one activated up, one down, with a neutral center-off position. This switch mounts directly into Blue Sea Systems Contura Water Resistant Panels and Contura Switch Mounting Panels, providing a sealed, integrated solution that keeps corrosion at bay. The compact footprint and black aesthetic integrate seamlessly into modern helm layouts.

Cruising anglers, commercial operators, and boat builders rely on Contura II switches for mission-critical redundancy and system isolation. The dual-circuit capability makes it ideal for switching between primary and backup systems, or managing independent loads that require split control. If you're upgrading an existing Contura panel or building a new console with industry-standard marine electrical architecture, this switch ensures your electrical systems remain dependable from coastal runs to offshore expeditions.
