I have just put together my horn (after many months of procrastinating!) and now I need to waterproof the switch and contacts. At the moment I have just wrapped them in electrical tape and put the switch in a little plastic bag sealed with electrical tape. I was wondering if this will be ok or if there is something more I have to do?
I guess it doesn't need to be 100% waterproof (except for the switch), but the contacts need to be apart so they don't short in the rain.
