Led Arcade Button?

Basically what I want to do is this

Or here if that doesn't show properly http://www.youtube.com/watch?v=oy9LjUzsZ10

But without a microcontroller. I need some guidance and direction for the circuit. I was looking to use a rgb led like this one http://www.paradisearcadeshop.com/en/button-leds/100-il-lumination-rgb-5vdc-led-0855742001002.html . It has a logic chip and resistor incorporated. Any suggestions on the circuit. This is going to illuminate a guitar killswitch and I want to conserve space that is why I do not want a controller. Thanks.

THIS would do the job for you.  The switch in the video shows a continuous red, then lights up magenta when pressed.  
To do this the common (for a common cathode RGB LED) would be connected to 0V.  
The red led terminal would be permanently wired to the supply with a suitable resistor (e.g. 270R for 5V) in series.  
The blue led would have a resistor too, and the terminal would be connected to the switch contact so when the switch is pressed the blue LED receives 5V and the button lights magenta (red + blue).
The connections would have to be reversed for a common anode LED.

Thank you that is very informative. I was thinking something along those lines might work. When my parts come in Ill let you know how it goes. When you say 0V, can I assume that is ground?
Yes, 0V is ground. 

I've just re-read your original question and found out what a killswitch is and there is going to be a problem.

For this to work, you will need a double pole switch and have the LED connection totally separate from the audio,  but I think the normal arcade buttons are single pole.  The reason is that when you press or release the button there will be a loud CLICK  from the amp, louder than the one mentioned in the video.  It's not possible to stop the LED voltage appearing on the audio with a single pole switch.

Hmmmmm. Im going to search for a DPDT version. Or a way to modify it, maybe with some sort of relay. I'll keep it simple and find a DPDP one I can use.

Im thinking I can use the arcade button shell over a switch like this http://www.taydaelectronics.com/2pdt-stomp-foot-pedal-switch-solder-lugs-2.html

http://www.ilovefuzz.com/viewtopic.php?f=151&t=17805 I just came across this diagram. Should work for what I want, right?
The LED you linked to does not have a logic chip. Yes it has integrated resistors on the board with the RGB LED but it still needs to be connected to a controller to light it up and change the colors.

I might have linked the wrong led. I have seen 555 timer circuits that drive rgb leds so I'm not convinced I need a controller.
No you don't need a controller. If the button is a SPDT then you can wire a different set of resistors to either side of the button. Then while the button isn't being pressed the LED will shine one color. When you press the button a different set of resistors are used making the LED shine a different color.
