Its double pole double throw wiring lets you reverse polarity or run two circuits from one lever, and the green illuminated halo keeps it easy to find and read after dark.\u003c\/p\u003e\n\n\u003cdiv class=\"nvn-description\"\u003e\n\u003cp\u003eThe Sierra Marine RK40700G is a heavy-duty rocker switch built for the helm, the dash, or any switch panel on your boat. It's an On-Off-On, double pole double throw (DPDT) switch rated for 20 amps at 12 volts DC, with a green illuminated halo so you can find it and read its state in the dark. Black rectangular body, clean lines, and the kind of no-nonsense build Sierra puts into its Marine Series electrical parts.\u003c\/p\u003e\n\u003cp\u003eHere's what makes a DPDT On-Off-On switch worth knowing about. It has a center Off position and two separate On positions, and it switches two circuits at the same time. That combination lets you do things a simple on\/off switch can't. The most common job is reversing polarity, which is exactly how you run a reversible load forward and back from a single switch. Think trim tabs, a jack plate, a reversible blower, or a small reversing motor. Flip it one way and the load runs one direction. Flip it the other way and the polarity swaps, so the load runs the other way. Center it and everything's off. You can also use the two poles independently to control a pair of separate circuits from one lever.\u003c\/p\u003e\n\u003cp\u003eThat flexibility is why Sierra calls this the Multi-Purpose Switch in its Marine Series. It's the kind of part you buy once and find three uses for while you're rigging the rest of the panel.\u003c\/p\u003e\n\u003cp\u003eThe green illumination is the detail you'll appreciate at night. On a dark helm, an unlit switch is just a guess. This one carries a green halo so it stands out on the panel and tells you at a glance what's live. It's a dependent-illumination design, so the green light is tied to the switched circuit rather than run off its own separate feed.\u003c\/p\u003e\n\u003cp\u003eAbout that 20 amp rating. That's a real, usable number for most accessory switching, running cabin and cockpit lights, a livewell pump, electronics, courtesy lighting, blowers, and similar loads. What we'd steer you away from is pushing a big continuous draw straight through any panel rocker. An anchor windlass, a big winch, or anything that pulls serious current is better handled by having the switch trigger a relay or solenoid, and letting that heavier device carry the load. You get the convenience of a helm switch without cooking the contacts. That's just good marine wiring practice, and it's how the folks who rig boats for a living do it. When in doubt, size for the load and switch a relay.\u003c\/p\u003e\n\u003cp\u003eInstallation is straightforward. It drops into a rectangular panel-mount cutout, so measure the switch body against your panel before you cut, and give yourself a little depth behind the panel for the terminals and your wiring. Use marine-grade tinned wire sized to the load, crimp on clean connectors, and fuse the circuit at the source. Boats vibrate, so a dab of thread locker or a lock washer on the terminal screws keeps everything tight over a season of pounding through chop.\u003c\/p\u003e\n\u003cp\u003eMount it where it gets a little shelter if you can. Any switch lives longer out of constant spray and direct sun, and a quick freshwater rinse of the panel after a salt day never hurts. Sierra builds this part to stand up out on the water, meeting or exceeding the original equipment it replaces, which is what you want when you're wiring something you'd rather not touch again for years.\u003c\/p\u003e\n\u003cp\u003eWho's it for? Anybody rigging or re-rigging a switch panel who needs a clean, illuminated, reversible switch that won't look out of place next to the rest of the helm. First boat or fifth, if you've got a reversible accessory or a couple of circuits to manage, this is a simple, honest part that does the job. It's the switch on its own, so plan on supplying your own wire, connectors, and fuse to finish the install.\u003c\/p\u003e\n\u003c\/div\u003e\n\n\u003ch2\u003eKey Features\u003c\/h2\u003e\n\u003cul class=\"nvn-features\"\u003e\n  \u003cli\u003eOn-Off-On, double pole double throw (DPDT) action so you can reverse polarity or switch two circuits from one lever\u003c\/li\u003e\n  \u003cli\u003e20 amp rating at 12 volts DC handles most accessory, lighting, and pump loads\u003c\/li\u003e\n  \u003cli\u003eGreen illuminated halo makes the switch easy to find and read on a dark helm\u003c\/li\u003e\n  \u003cli\u003eRectangular black body drops into a standard panel-mount cutout for a clean, flush look\u003c\/li\u003e\n  \u003cli\u003eDependent illumination ties the green light to the switched circuit, so it shows you what's live\u003c\/li\u003e\n  \u003cli\u003eMaintained On-Off-On positions stay where you set them, no need to hold the rocker\u003c\/li\u003e\n  \u003cli\u003eMarine Series build from Sierra, engineered to meet or exceed the OEM part it replaces\u003c\/li\u003e\n  \u003cli\u003eGreat for reversible loads like trim tabs, jack plates, and reversible blowers, or for triggering a relay on heavier circuits\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cdiv class=\"nvn-trust\"\u003e\n  \u003ch2\u003eWhy Buy from NVN Marine\u003c\/h2\u003e\n  \u003cul\u003e\n    \u003cli\u003eAuthorized Sierra Marine reseller, full manufacturer warranty\u003c\/li\u003e\n    \u003cli\u003eNMEA member and ABYC certified, advice from real boat techs\u003c\/li\u003e\n    \u003cli\u003eSame-day shipping before 3 PM ET on in-stock items\u003c\/li\u003e\n    \u003cli\u003eNY headquarters and Fort Lauderdale flagship retail store\u003c\/li\u003e\n  \u003c\/ul\u003e\n\u003c\/div\u003e\n\n\u003ch2\u003eFrequently Asked Questions\u003c\/h2\u003e\n\u003cdiv class=\"nvn-faq\"\u003e\n  \u003cdetails\u003e\n    \u003csummary\u003eWhat does On-Off-On DPDT mean on this switch?\u003c\/summary\u003e\n    \u003cp\u003eDPDT stands for double pole double throw, and On-Off-On means there's a center Off position with an On position on either side.
