Rated at 20 amps, it glows when a circuit is live, wears a black face that blends into any switch bank, and ships with a neoprene mounting gasket to seal the panel cutout against spray.\u003c\/p\u003e\n\n\u003cdiv class=\"nvn-description\"\u003e\n\u003cp\u003eThe Sierra RK19730TP is an illuminated On-Off-On rocker switch built for the helm, the dash, or any 12-volt panel on your boat. It's a simple part that does a specific job well. Flip it up, flip it down, or leave it in the center and the circuit's off. Sierra rates it at 20 amps on a 12-volt system, which covers most of the accessories you'd actually wire to a switch like this.\u003c\/p\u003e\n\u003cp\u003eHere's what On-Off-On actually means, because it matters when you wire it in. The switch has three positions. Center is off. Push the rocker one way and it feeds one circuit. Push it the other way and it feeds a second circuit. So a single switch can run two separate loads, or drive something that goes two directions, with a clean off in the middle. If you only need a plain on and off, you just wire one side and ignore the other position. That flexibility is why these live behind so many marine dashboards.\u003c\/p\u003e\n\u003cp\u003eThe rocker is illuminated, so it glows when the circuit is live. That sounds like a small thing until you're running dark and want to know at a glance whether the blower or the deck light is still on. A lit rocker tells you without reaching for a flashlight. The face is black, so it disappears into most panel layouts and doesn't clash with the rest of your switch bank.\u003c\/p\u003e\n\u003cp\u003eEvery switch ships with a neoprene mounting gasket. That gasket sits between the rocker body and your panel, sealing the cutout against the spray and damp that find their way onto every console. It's not a submersible part and we won't pretend it is, but the gasket keeps the everyday splash and dew out of the mounting hole, which is exactly what you want on an open boat. Mount it somewhere it won't sit underwater and it'll give you years of service.\u003c\/p\u003e\n\u003cp\u003eWho's this for? Anyone adding or replacing a switch on a boat. Maybe your old rocker cracked or stopped lighting up. Maybe you're wiring in a new bilge blower, a set of courtesy lights, a livewell pump, or a wiper, and you want a marine-grade switch instead of something off the auto-parts wall. Sierra's whole line is engineered for the marine environment, meaning the materials and the build are meant to stand up to salt, humidity, and vibration better than a generic switch would. This is a straight, honest replacement or upgrade.\u003c\/p\u003e\n\u003cp\u003eInstallation is straightforward for anyone comfortable with 12-volt DC wiring. The rocker drops into a panel cutout, the neoprene gasket seals it, and you land your wires on the terminals on the back. Feed power to the common, run your loads off the two switched positions, and you're done. If you're replacing an existing rocker, snap a photo of the old wiring first so you match it. And always pull the battery disconnect before you start poking around behind the dash. Basic stuff, but worth saying.\u003c\/p\u003e\n\u003cp\u003eA quick word on what it isn't. This isn't a high-amperage switch for a windlass or a big DC motor that pulls past 20 amps. It isn't a fully sealed, submersible toggle for a spot that goes underwater. And it's a 12-volt part, so keep it on 12-volt circuits. Match the switch to the load and it'll do its job for a long time. Push more current through it than it's rated for and you'll cook it, same as any switch.\u003c\/p\u003e\n\u003cp\u003eIf you're standardizing a panel, the On-Off-On illuminated black rocker is one of the most useful shapes to keep on hand. It handles single on-off duties, two-circuit duties, and reversing duties, all from the same part. That's why it's a staple in the Sierra switch lineup, and why it's an easy one to trust when you're rigging or repairing your own boat.\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 action gives you three positions, so one switch can run two separate circuits with a clean off in the middle\u003c\/li\u003e\n  \u003cli\u003e12-volt, 20-amp rating handles nav lights, blowers, livewell pumps, wipers, and most helm accessories\u003c\/li\u003e\n  \u003cli\u003eIlluminated rocker glows when the circuit is live, so you can see what's on at a dark helm\u003c\/li\u003e\n  \u003cli\u003eNeoprene mounting gasket included, sealing the panel cutout against everyday spray and damp\u003c\/li\u003e\n  \u003cli\u003eBlack rocker face blends into any switch bank or console panel\u003c\/li\u003e\n  \u003cli\u003eMarine-grade Sierra build, made to stand up to salt, humidity, and vibration\u003c\/li\u003e\n  \u003cli\u003eDrops into a panel cutout and wires to the rear terminals for a clean flush finish\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 mean on this switch?\u003c\/summary\u003e\n    \u003cp\u003eIt's a three-position rocker.
