Try Digi-Key, I've bought a few things from them...resistors and such and some other odds and ends...a few two stage type clickies for Q3 mods. It's kind of like looking at another language similar to yours ie French - English. They've got mostly the same letters in their words, and some are even the same, but you still can't understand. It's a specific vocabulary used in a way that assumes you know certain things (which I do not). So think of it as having to learn another skill to go with flashlight modding as a whole. They sent me a free catalog, it's about the size of a phone book.
There are also people/business' that will custom design and make switches for you, but I have no idea how outrageous that can become.
Good luck.
