If you want the aircraft look you can also try here:
B&C Specialty Products - Switches
Used them a lot for the plane. They have every combination you can imagine. It looks like a short list but it's because the first page is just the number of poles. If you click single or double pole then you can choose any combination of off/on/momentary you want.
I've also had really good luck with these guys, who carry a lot of the weird stuff you sometimes want in automotive work, like weather-tight power connectors, etc:
Toggle Switches | Automotive & Marine Toggle Switches | Waytek, Inc - Page 1 of 6
And if you're on a budget, keep your eye on these guys:
Switches - Toggle | All Electronics Corp.
All Electronics, AllTronics, and a few other electronics shops have all sorts of funky things. If you like lighted or oddly-shaped switches, they're a good place to look.
