Thumbwheels, Switches, Etc - Where to Buy

Can somebody suggest some good sources for a good selection of input hardware such as thumb wheel, switches, analog knobs, etc?

Everything we do is on an HMI (except the E-stop of course) but I'd like to add some hardware inputs.

My first choice is Allied Electronics. I like their really fast service.

My second choice is Newark Electronics.

Both can easily be googled.

There are many others, All Electronics, etc, that you can find, specially in the electronics magazines. But they are generally slower.

Digikey and Mouser also
