Water proof switch

My underbonnet compressor switch became possessed with evil spirits after a couple of years (compressor starting by itself after 4by had been parked for a few hours). This was happenning a couple of times/week. It didn't completely flatten any of my batteries - but that was good luck rather than good management. I ended up pulling the switch out altogether.

I went to AutoPro (or something similar) and found a bog standard 12V 20A switch (for about 12 bucks) and found a rubber switch "boot" that fits over the toggle portion of the switch for about $4.50. The rubber boot has an integral metal thread that screws down over the switch mounting thread.

I couldn't say if the switch is waterproof now, but it should be able to take the occasional squirt from a hose whilst cleaning the engine bay.

I'll see if I can find the packet the switch came in so I can tell you the brand.

Any good marine store should have a few... those places are absolute goldmines!

The cheapest and easiest option (depending on the location of the switch) is a normal baloon and some electrical tape. simply put the switch inside the baloon and tape up the end around the wires very tight. not much good if near heat or the switch has to mounted somewhere, but I used to use that method to waterproof remote control car parts when I was a kid and then take em off road......mmmm no wonder I've got a 4b now!!

Ray go with 4BY, the marine chandlery shops have an amazing array of water proof switches and they arent that much dearer than autobarn/supercheap! Some come fused and sealed etc in a nice setup, save you alot of work water proofing!!

Goodluck! Matt.
