hello!
I just thought I would share one of my favorite web sites for crazy buttons. They're designed for computer mods, but many work for currents much higher than you'd see in a computer, and a few even are rated for AC, like the big old mushroom buttons that you just have to press once you see it, and the millitary-style flip-cover switches. Resellerratings.com seems to like them ok, so I'll advocate them:
http://directron.com/switches2.html Great selection, little pricey, but you get what you pay for, and switches see a lot of wear and tear.
