Blue Sea Systems 4138 WeatherDeck Toggle Switch Boot, Black

Works both on and off!

it is momentary "on" switch

Weatherproof but made sure installed upside down so water can drain off. Works well.

Nicely made switch, BUT be aware that it only fits the Blue Seas Weatherdeck panels! The switch is apparently designed for a panel with about a 1/4" thickness, so the threaded neck is not threaded all the way down. I had intended to install this switch in an existing sheet metal panel (1/16" thick or so) but the locking collar won't hold the switch tight in such a thin panel. Yes, Blue Seas does say this switch is "for Weatherdeck panels", but they don't specifically say it won't fit other metal panels.

I have been through countless good quality parts store switches with lifetime warranties. The local parts guys have never refused to replace one free of charge, but replacing switches on a regular basis is a hassle and, quite frankly, many times you don't know it's busted until you turn it on and it fails to light. Even though my light switches on the ol' tractor weren't "in the elements" directly, I decided that the failure had to be seepage related and decided to try one of these. I have not has a failure on the original switch, while I have been through two of the old style during the course of my experiment. To me that's proof enough. These switches and boots are not the cheapest, but they are well-made and hold up. Worth the price. Make sure you order the switch with the boot. They DO NOT come as a set!!!!!!!!!!!!!
