## Description

Specially manufactured by Carling Technologies for use in Blue Sea Systems" WeatherDeck Panels When mounted with a WeatherDeck Toggle Switch Boot Rated IP67-temporay immersion for 30 min Nickel-plated brass and phenolic non-corrosive construction.

Review: Good switch at good value - Weatherproof but made sure installed upside down so water can drain off. Works well.
Review: Keeps the lights on the tractor running - 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!!!!!!!!!!!!!

## Questions & Answers

**Q: what is the barrel diameter and other dimensions?**
A: The diameter is 7/16" round and 1/2" long with a backing nut to tighten to the thickness of the material that it feeds through. You need to allow 1/8" of the barrel to protrude past the material the switch is mounting into to allow the finishing nut to screw onto the end of the barrel. The electrical portion of the switch is 1" long x 5/8" wide x 1/2" deep with two electrical terminals. 1/2" deep does not include the electrical terminals its approximately 1" with the electrical terminals.

**Q: do you ground it? only has 2 connections on back.**
A: The manufactures website. You would not ground this switch it is only a make or break connection (on/off)https://www.bluesea.com/products/4150/WeatherDeck_Toggle_Switch_SPST_-_ON-OFF

**Q: Which switch do I buy to wire heated handlebar grips that have off-low-high as the factory settings?**
A: Spdt, On-off-on . wiring connections, assuming your grips have three wires, one would be ground and wired to ground. other two wires would be hi and low circuits in grips and would be connected to the two outside poles of switch and battery power connected to switch center pole.

**Q: do you have electrical reset switches for an air compressoe?**
A: Put "Electrical reset switch for air compressor" in your search engine and it will tell you who has them.
