Carlton, Thanks. Yes, I feel like I got pretty lucky with these switches. In my opinion they make the build. I did a lot of searching and think these are a great choice for this application. They are fully sealed and high quality. Not cheap ($50/ea), but ideal for the application. I bought them at Digikey.com. I did not use the mounting hardware, but simply rolled electrical tape around the threads, reversed the tape halfway so the "sticky" side was exposed and wedged them into the bar ends like bar end plugs. They come with the rubber "seal" rings shown below, but the fit is so good, I just put a little silicone on the bar ends to form a seal. The Switches are rated waterproof/dustproof and I soldered the wires and sealed the connections, so I am not concerned about exposure to the elements.
