Illuminating buttons
Well, I have a idea which may not be the best but you can use it if you don't get those switch. Have you tried using acrylic sheet ?? thats a very good and neat option and you can get the job done with less number of led's &amp; less power consumption.

as its very easy to work with these sheets and for better illumination around the switch etch the acrylic sheet, Its going to look gr8 :)
