Featuring a Single Pole Single Throw (SPST) configuration with a spring-return OFF-(ON) action, this switch remains active only while actively pressed. This specific switching logic makes it the ideal interface for temporary-activation accessories such as marine horns, windlasses, windshield washers, starter solenoids, and manual bilge pump overrides.\u003c\/p\u003e\u003cp\u003eStandard switches often fail prematurely when exposed to the constant pounding of waves, corrugated off-road tracks, or extreme temperature fluctuations. The Blue Sea Systems Contura II series addresses these vulnerabilities through heavy-duty internal mechanics and an integrated environmental sealing gasket. Whether installed on an exposed boat flybridge, an open-cab agricultural vehicle, or a custom 4WD canopy setup, this rocker switch reduces the risk of electrical shorts, corrosion-induced voltage drop, and mechanical failure.\u003c\/p\u003e\u003ch3\u003eEngineered for Durability and Tactile Precision\u003c\/h3\u003e\u003cp\u003eDesigned specifically for seamless integration, this unit snaps directly into Blue Sea Systems Contura Water Resistant Panels and Contura Switch Mounting Panels. The exterior features a hard-wearing black Contura II actuator equipped with a non-slip, dimpled tactile surface. This allows operators to easily identify and actuate the switch by feel alone in low-light conditions, rough seas, or while wearing gloves.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMomentary OFF-(ON) Action:\u003c\/strong\u003e Spring-return mechanism ensures circuits are only energised while the actuator is held down, preventing accidental continuous operation of high-draw momentary loads.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnvironmental Sealing:\u003c\/strong\u003e An integrated gasket and high-impact housing protect internal contacts against moisture ingress, salt spray, and dust.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eExtreme Stress Resistance:\u003c\/strong\u003e Specifically tested to withstand continuous high-frequency vibration, physical shock, and rapid thermoshock without mechanical degradation.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTactile Contura II Actuator:\u003c\/strong\u003e Black rocker surface features raised dimples for positive grip and confident operation in wet conditions.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStreamlined Installation:\u003c\/strong\u003e Equipped with rear quick-connect male tab terminals for secure electrical wiring and direct snap-in mounting for compatible Blue Sea Contura panels.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eApplications and System Integration\u003c\/h3\u003e\u003cp\u003eUpgrading to marine-grade switching components is essential for maintaining the integrity of low-voltage DC distribution systems. By preventing moisture and salt from reaching the conductive terminals, the BS-7930B mitigates the risk of parasitic draws and intermittent circuit faults. It serves as either a direct replacement switch for existing Blue Sea Systems panels or as a foundational component for custom-built dashboards in boats, caravans, and commercial service vehicles.\u003c\/p\u003e\u003ch3\u003eUpgrade Your Control Panel\u003c\/h3\u003e\u003cp\u003eEnsure dependable momentary switching in your marine or off-grid electrical system by integrating the Blue Sea Contura 2 SPST OFF-(ON) Switch into your next panel build or maintenance upgrade.\u003c\/p\u003e","brand":"Blue Sea","offers":[{"title":"Default Title","offer_id":43631720661053,"sku":"BS-7930B","price":21.62,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0602\/3918\/3933\/files\/blue-sea-contura-2-spst-off-on-switch-bs-7930b.png?v=1792905502","url":"https:\/\/www.solar4rvs.com.au\/products\/blue-sea-contura-2-spst-off-on-panel-mount-switch-black","provider":"Solar 4 RVs","version":"1.0","type":"link"}
