Featuring a Single Pole Double Throw (SPDT) configuration with two active ON states, this rocker switch allows a single common input to seamlessly alternate between two distinct circuit paths. It is an ideal component for systems that require a constant selection between two operating states without a centre off position, such as switching between dual battery monitoring banks, alternating between primary and secondary bilge pumps, or selecting different lighting modes in a 4WD canopy.\u003c\/p\u003e\n\n\u003ch3\u003eEngineered for Extreme Environmental Resistance\u003c\/h3\u003e\n\u003cp\u003eStandard consumer-grade switches often fail prematurely when exposed to the elements, leading to corroded contacts, voltage drop, or complete circuit failure when you are miles offshore or deep in the outback. Blue Sea Systems designs the Contura series specifically to mitigate these risks. This switch is rigorously tested to resist vibration, shock, thermoshock, moisture, and salt spray.\u003c\/p\u003e\n\u003cp\u003eWhether mounted on an exposed boat flybridge, an open centre console, or the dashboard of an off-road touring vehicle, this switch maintains reliable electrical continuity. Its resilience against thermoshock ensures the housing and internal mechanisms will not crack or warp during rapid temperature fluctuations, while its salt spray resistance prevents internal terminal degradation in corrosive coastal environments.\u003c\/p\u003e\n\n\u003ch3\u003eErgonomic Design and Seamless Panel Integration\u003c\/h3\u003e\n\u003cp\u003eBuilt for practical operation in dynamic conditions, the switch features a distinctive dual-textured actuator. The upper section comprises a red rocker clearly marked with a white battery symbol and \"ON\" text for immediate visual identification, while the lower section features a black textured finish that provides tactile grip for ergonomic switching, even with wet or gloved hands.\u003c\/p\u003e\n\u003cp\u003eInstallation is straightforward thanks to the standard Contura style snap-in bezel, which locks securely into compatible mounting panels and water-resistant dash panels. The rear-mounted spade terminals allow for clean, secure electrical connections using standard female blade connectors, simplifying both new custom panel builds and retrofits.\u003c\/p\u003e\n\n\u003ch3\u003eKey Features and Benefits\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSPDT ON\/ON Configuration:\u003c\/strong\u003e Provides two active switch positions, allowing one pole to reliably toggle between two separate circuit outputs.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMarine-Grade Durability:\u003c\/strong\u003e Explicitly rated to withstand moisture and salt spray, reducing the risk of corrosion in coastal and marine applications.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMechanical Resilience:\u003c\/strong\u003e High resistance to continuous vibration and physical shock makes it well suited for rough corrugated roads and choppy waters.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThermoshock Protection:\u003c\/strong\u003e Engineered to endure rapid temperature changes without compromising structural or electrical integrity.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTactile Actuator Design:\u003c\/strong\u003e Combines a high-visibility red upper rocker (with battery icon) and a textured black lower rocker for confident, non-slip operation.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandardised Mounting:\u003c\/strong\u003e Features a snap-in bezel for easy integration into Blue Sea Systems Contura panels and standard rectangular dashboard cutouts.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eIdeal Applications\u003c\/h3\u003e\n\u003cp\u003eThis versatile rocker switch is suited for a wide array of low-voltage control panels across marine, recreational vehicle, and industrial sectors:\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMarine Vessels:\u003c\/strong\u003e Ideal for helm panels, flybridges, and open boats requiring weather-resistant switching between navigation equipment, pumps, or battery isolators.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e4WDs and Caravans:\u003c\/strong\u003e Dependable circuit selection for dual battery management displays, auxiliary fuel transfer systems, or dual-colour work lighting.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIndustrial and Specialty Vehicles:\u003c\/strong\u003e Reliable two-state control for agricultural machinery, emergency service vehicles, and mobile service bodies exposed to dust, moisture, and heavy vibration.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eUpgrade Your Control Panel\u003c\/h3\u003e\n\u003cp\u003eEnsure your electrical system remains responsive and reliable in the toughest Australian conditions.
