How to wire Illuminated buttons so that they light up when pressed ?

Hi everyone !
I'm in the process of building a Beatmania IIDX controler similar to this one : so I would like the LEDs (5V) to light up when the buttons are pressed. I have a mini-PAC from ultimarc which works great, I took the 5V from a USB port to test the LEDs and it works just fine, so all I need now is to link the two ^^
the switch has 3 pins (Common, Open and closed) and the button itself has two pins (+ and -) to feed the LED.
I've been searching for a guide but I couldn't find any, so could anyone explain how I can do that ?

Thanx !

PS : I think You've guessed it by now, but I have absolutely no experience in electronics, so try to explain as if you were talking to a 3 years old ;-)

Oh wow ! I didn't expect it to be that complicated. Well I'll probably do it eventually, but in the meantime if someone has something a little simpler that would be appreciated ^^

Thanx for the link though, bookmarked !

Nice link. That's not too bad a circuit, and you can hook up 6 buttons to one inverter chip. You could even hook the inverter up to you 5v usb power line for power and ditch the battery.

Bookmarked here too!

Wouldnt something like this work?
Of course if youhave more than one or two buttons you may want to get the 5 vdc for the LEDs from the computer power supply. USB is limited to half a amp in best scenario, Im sure.
