I'm getting to the phase of my project where I need to construct the dashboard. Everything is set except for the buttons. I've googled and searched for this but haven't had a ton of success. Does anyone know of a good place to buy momentary pushbuttons? I've looked into Radio Shack, but they only really have one decent-looking kind. What I'd like is something that you can surface mount which will look nice (i.e. not a switch that's meant to be pressed by something else and not be seen). I'd also like two or three different shapes and sizes. Possibly an oval shape. All the places I've found online only do distribution and not to consumers.
Also related, I'd like a rotary knob where it can turn an infinite number of times, and it can perform two operations - based on whether it's turned clockwise or counter-clockwise. What is this called, and do you know where I could find this? Thanks!
Allied Electronics has a zillion different buttons of all flavors, but it's a bit difficult to browse the inventory without a catalogue (a 2" thick tome they will happily send to you.)
As for your knob - a quadrature encoder would do what you're talking about, but it does require some electronics. There was a thread a little while back discussing this (I think it was in the Hardware Development forum).
i am in need of a similar rotary switch. for my carputer, i used the existing receiver because it had an aux. input. therefore, i just buried it in my dash and then mounted my touchscreen in front of it. however, i would like to be able to control the volume on it, so i need to solder into the stereo and extend the volume knob. it is the same as the one you described...it spins infintely (there is no max). it is similar to a mouse's scroll wheel...
does anybody know what this is called, or where to buy a rotary switch of this kind????
digikey.com should have something. They got all sorts of ****
edit: qtrox or qrox cant remember has touch sensitive buttons if you felt like using them. Then you can make almost anything the button
fount it http://qprox.com
man i wasnt even close
also look on www.bit-tech.net they make a lot of buttons out of acrylic rod infront of a momentary switch with an led mounted in it. looks good.

i got mine from www.frozencpu.com. They've got some amazing good quality stuff, but on the expensive side.

It is called a rotary encoder. You can interface one by building your own circuit or disecting a mouse. Check these threads:Originally Posted by bdd
Some nice parts:
I hope to have a website for my project again, once I get some webspace.
