Featuring an \u003cstrong\u003eON-OFF-ON configuration\u003c\/strong\u003e with a dedicated centre-off position, this Single Pole Double Throw (SPDT) rocker switch allows seamless management of dual-function accessories or two-circuit applications from a single panel cutout. Whether you are outfitting a marine helm, a 4WD dashboard, or an off-grid caravan control panel, this switch provides dependable mechanical and electrical performance.\u003c\/p\u003e\u003ch3\u003eBuilt for Harsh Australian Environments\u003c\/h3\u003e\u003cp\u003eStandard automotive switches often fail when exposed to continuous vibration, high humidity, or coastal air. The Contura II series is specifically manufactured to resist vibration, physical shock, thermoshock, moisture, and corrosive salt spray. An integrated foam weatherproof gasket forms a protective seal around the mounting aperture, helping to reduce the risk of water ingress and terminal corrosion behind your dash or switchboard. This environmental resilience prevents premature electrical failure and intermittent circuit dropouts during off-road travel or rough sea conditions.\u003c\/p\u003e\u003ch3\u003eErgonomic Design and Visual Circuit Feedback\u003c\/h3\u003e\u003cp\u003eOperating switches in wet, dark, or bumpy conditions requires intuitive tactile and visual cues. The Contura II black actuator features a raised, textured grip surface with tactile bumps, providing non-slip operation when your hands are wet or gloved. To eliminate guesswork during night navigation or low-light operation, the switch incorporates dual red lenses: a top square lens and a bottom horizontal bar lens for clear visual status feedback when circuits are active.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSPDT ON-OFF-ON Configuration:\u003c\/strong\u003e Controls two separate circuits from a single common power source with a positive centre-off position.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eExtreme Environmental Resistance:\u003c\/strong\u003e Engineered to withstand vibration, shock, thermoshock, moisture, and salt spray.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDual Red Lenses:\u003c\/strong\u003e Top square and bottom bar lenses provide clear visual circuit status indication.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTactile Contura II Actuator:\u003c\/strong\u003e Raised grip surface ensures secure, non-slip manual operation in wet or bumpy conditions.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIntegrated Weatherproof Gasket:\u003c\/strong\u003e Foam seal helps prevent moisture and dust ingress into the panel cavity.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeamless Panel Integration:\u003c\/strong\u003e Directly fits Blue Sea Systems Contura Water Resistant Panels and Contura Switch Mounting Panels.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eVersatile Dual-Circuit Applications\u003c\/h3\u003e\u003cp\u003eThe Single Pole Double Throw ON-OFF-ON layout is an essential component for managing multi-state electrical hardware in 12V and 24V DC systems.
