Featuring a Double Pole Double Throw (DPDT) configuration, this three-position switch offers one momentary ON position, a central OFF state, and one maintained ON position. This specific action is ideal for applications requiring temporary activation alongside a continuous operating mode, such as dual-speed wiper motors, bilge pumps with manual override, or complex lighting arrays.\u003c\/p\u003e\n\n\u003ch3\u003eEngineered for Harsh Environments\u003c\/h3\u003e\n\u003cp\u003eStandard automotive switches often fail prematurely when exposed to corrosive coastal air or constant mechanical movement. The Contura II series is purpose-built to mitigate these risks, featuring a durable thermoplastic housing and an integrated mounting gasket that seals the panel cut-out against water ingress. Specifically engineered to withstand severe vibration, physical shock, thermoshock, moisture, and salt spray, it reduces the risk of electrical shorts and terminal corrosion in open-cockpit boats, 4WD canopies, and off-road caravans.\u003c\/p\u003e\n\n\u003ch3\u003eErgonomic Control and Seamless Integration\u003c\/h3\u003e\n\u003cp\u003eDesigned for intuitive operation in low-light or turbulent conditions, the black Contura II actuator features a textured, non-slip surface with raised ergonomic bumps for positive tactile feedback. The integrated red indicator lens provides clear visual confirmation when the circuit is active, improving operational awareness at the helm or dashboard. Rear male spade terminals ensure straightforward, secure wire termination during installation.\u003c\/p\u003e\n\n\u003ch3\u003eKey Features and Benefits\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDPDT (ON)-OFF-ON Action:\u003c\/strong\u003e Combines momentary and maintained switching in a single unit with a positive centre-off position to prevent accidental cross-activation.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMarine-Grade Environmental Protection:\u003c\/strong\u003e Tested for high resistance to salt spray, moisture, thermoshock, and heavy vibration.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWater-Resistant Panel Seal:\u003c\/strong\u003e Includes a perimeter sealing gasket to protect rear wiring and busbars from splashes and washdowns.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTactile Contura II Actuator:\u003c\/strong\u003e Black non-slip rocker with raised contours and an integrated red status lens for easy identification.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDirect Panel Compatibility:\u003c\/strong\u003e Designed to snap directly into Blue Sea Systems Contura Water Resistant Panels and Contura Switch Mounting Panels.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eCommon Applications\u003c\/h3\u003e\n\u003cp\u003eThe versatile six-terminal DPDT layout allows this switch to control two separate circuits simultaneously or manage polarity-reversing setups when wired accordingly.
