It's non-lighted, finished in black, and uses a snap-in design that clicks into a standard rectangular panel opening. Wire it up for lights, pumps, or wipers and you're back in business.\u003c\/p\u003e\n\n\u003cdiv class=\"nvn-description\"\u003e\n\u003cp\u003eThis is the T-H Marine On-Off rocker switch, a simple 12-volt DC switch built to run a single circuit on your boat. It's rated for 20 amps, non-lighted, finished in black, and shaped like a standard rectangular rocker. If you've ever had a switch corrode out on the dash and leave a pump or a light dead in the water, you already know why a clean replacement matters. This one's made to drop into that spot and get the circuit working again.\u003c\/p\u003e\n\u003cp\u003eThe rating is the part that matters most. Twelve volts DC, up to 20 amps. That's plenty of headroom for the loads most boaters run through a single toggle, from LED and incandescent lights to smaller pumps and wiper motors. It's a straight on-off switch, so one press energizes the circuit and the other kills it. No momentary action, no three-position modes, just a clean make-or-break for whatever you wire to it. Keep the load under the 20-amp ceiling and it'll do its job without complaint.\u003c\/p\u003e\n\u003cp\u003eMounting is the snap-in style. You cut or reuse a rectangular opening in the dash, console, or switch panel, and the body clicks into place from the front. That makes it a friendly swap for anyone redoing a helm or replacing a tired switch one at a time. Wire your feed and load to the terminals on the back, snap it home, and you're done. Because it's the common rocker footprint, it lines up neatly next to your other switches instead of leaving an oddball hole in the panel.\u003c\/p\u003e\n\u003cp\u003eSo what do people actually run on it? Lights, pumps, and wipers, per T-H Marine's own listing. Think nav and anchor lights, courtesy and cockpit lighting, a livewell or aerator pump, a washdown or bilge pump within the amp rating, or a windshield wiper motor on a hardtop console. Anywhere you want a dedicated on-off for one accessory, this covers it. Anglers use them across the console for lights and aeration. Cruisers use them for cabin and deck circuits. It's the kind of part you end up buying a few of.\u003c\/p\u003e\n\u003cp\u003eIt's non-lighted, so there's no backlight or indicator glow when the circuit is on. Some folks prefer that, especially for night running where you don't want extra light in your eyes at the helm. The black housing keeps it low-key and blends into most modern dash panels and switch clusters. If your boat's panel is already black or dark gray, this disappears into it the way a good switch should.\u003c\/p\u003e\n\u003cp\u003eOne tip from the rigging bench: protect the circuit, not just the switch. A rocker rated for 20 amps still wants a fuse or breaker sized to the wire and the load ahead of it, so a dead short trips the protection instead of cooking the switch or the harness. Check what the accessory draws before you wire it in. Most lights and small pumps sit well under the ceiling, but a couple of pumps ganged onto one switch can add up faster than you'd think. Size it right and this switch will outlast a lot of the other hardware on the dash.\u003c\/p\u003e\n\u003cp\u003eT-H Marine has been building boat rigging and accessories for decades, and switches like this are the bread-and-butter gear that keeps a boat wired and working. It's an honest, no-drama part. If you need a basic 12-volt on-off for a light, a pump, or a wiper and you want it to match the rocker switches already on your dash, this is a straightforward pick. Buy one for a quick repair or grab a handful for a full panel rebuild, and wire it in with confidence.\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 function, single-circuit make-or-break control for one accessory\u003c\/li\u003e\n  \u003cli\u003e12 Volt DC rated, matches standard boat electrical systems\u003c\/li\u003e\n  \u003cli\u003e20 Ampere capacity, handles lights, small pumps, and wiper motors with headroom\u003c\/li\u003e\n  \u003cli\u003eSnap-In design, clicks into a rectangular panel opening from the front for a quick swap\u003c\/li\u003e\n  \u003cli\u003eRectangle rocker shape, lines up with common switch panels and clusters\u003c\/li\u003e\n  \u003cli\u003eNon-lighted, no backlight glare at the helm on night runs\u003c\/li\u003e\n  \u003cli\u003eBlack housing, blends into modern dark dash panels\u003c\/li\u003e\n  \u003cli\u003eFor lights, pumps, and wipers, a versatile dedicated switch for 12V accessories\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 T-H Marine Supplies 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 can I run on this T-H Marine rocker switch?\u003c\/summary\u003e\n    \u003cp\u003eIt's a 12-volt DC on-off switch rated for 20 amps, and T-H Marine lists it for lights, pumps, and wipers.
