Flip the switch right through the rubber. It's cheap insurance for every exposed switch at your helm, dash, or console.\u003c\/p\u003e\n\n\u003cdiv class=\"nvn-description\"\u003e\n\u003cp\u003eOpen water and electrical switches have never gotten along. Spray finds every gap, and the first place it gets in is the base of a toggle handle, right where the stem passes through the panel. The Sierra MP39240-1 is the simple fix for that. It's a black rubber sealing boot that covers a standard toggle switch and keeps moisture and dirt out of the one spot that always fails first. It's a small part. But it's the difference between a switch that still works in year five and one that's corroded and intermittent by the end of your first wet season.\u003c\/p\u003e\n\u003cp\u003eThis boot fits any standard toggle with a 15\/32 inch stem. That's the most common toggle size out there, so chances are the switches already on your dash, helm, or console will take it. The rubber covers the toggle handle completely, and you flip the switch right through it, so there's no change to how the switch feels under your thumb. The seal sits where the stem meets the panel and closes off the path water uses to wick down into the contacts.\u003c\/p\u003e\n\u003cp\u003eThink about where your switches actually live. The bilge pump switch down low that catches bilge mist. Nav light and livewell switches on an open center console that sees rain and spray all day. Trim, blower, and washdown switches crowded onto a helm panel. Add in deck wash and raw-water switches that sit out in the open, and you start to see how many switches on a boat never really get a break from the weather. Those are the ones that corrode, and those are exactly the ones this boot is built to protect. We rig these onto new switch panels as a matter of course, and we point anyone chasing a flaky switch toward them first.\u003c\/p\u003e\n\u003cp\u003eIt's black rubber, flexible, and it keeps its shape in sun and salt a lot better than a bare metal switch nut holds up. The rubber flexes with every throw of the switch and springs right back to re-seal. Salt and sun are hard on exposed switch hardware, and this boot takes that beating so the switch underneath doesn't. And because it's black, it blends into most dark dashes and panels instead of standing out, so a row of booted switches still looks clean.\u003c\/p\u003e\n\u003cp\u003eInstalling one takes about a minute. It's a boot nut, so it threads onto the switch's 15\/32 inch stem and snugs down against the panel, holding itself in place with no extra hardware to source. Seat the lip flat against the panel and snug it just enough to sit tight. You don't need to crank on it, since the rubber does the sealing, not brute force on the threads. You don't touch the wiring and you don't replace the switch. If you're building a panel from scratch, put a boot on every switch before you bolt the panel in. It's a lot easier to do on the bench than reaching blind behind a finished dash.\u003c\/p\u003e\n\u003cp\u003eA couple of honest notes before you order. This one's sold as a single boot, so count your switches and buy one per switch. It's sized for standard 15\/32 inch toggles, not the tiny sub-mini toggles or oversized heavy-duty stems, so check what your switch uses first. And it seals the front of the switch where water gets in. It won't rescue a switch that's already corroded inside. If a switch is already acting up, replace it and boot the new one so you're not back here in a month.\u003c\/p\u003e\n\u003cp\u003eFor the price of a coffee, it's some of the cheapest insurance on the whole boat. Keep a few in the parts drawer. The first time a nav light keeps right on working through a downpour because you booted that switch, you'll be glad you spent the couple of bucks.\u003c\/p\u003e\n\u003c\/div\u003e\n\n\u003ch2\u003eKey Features\u003c\/h2\u003e\n\u003cul class=\"nvn-features\"\u003e\n  \u003cli\u003eFits standard 15\/32 inch toggle switch stems, the most common size on marine dashes and helms\u003c\/li\u003e\n  \u003cli\u003eBlack rubber construction flexes with the switch and springs back to keep its seal\u003c\/li\u003e\n  \u003cli\u003eSeals out moisture and dirt at the base of the handle, where switches corrode first\u003c\/li\u003e\n  \u003cli\u003eCompletely covers the toggle handle, so you operate the switch right through the boot\u003c\/li\u003e\n  \u003cli\u003eBoot nut design threads onto the switch stem and holds itself in place, no extra hardware\u003c\/li\u003e\n  \u003cli\u003eSold as a single boot, so you can protect one switch or a whole panel\u003c\/li\u003e\n  \u003cli\u003eLow-profile black finish blends into most dark dashes and switch panels\u003c\/li\u003e\n  \u003cli\u003eInstalls without touching the wiring, on the bench or behind a finished dash\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 size toggle switch does this boot fit?\u003c\/summary\u003e\n    \u003cp\u003eIt's made for standard toggle switches with a 15\/32 inch stem, which is the most common toggle size on marine dashes and panels.
