Ok, I already tried with no result, so I'm going to ask here.
I have a small illuminated pushbutton, the contacts on the bottom are L+ L- C NO and NC
How do I wire my 5v from gpwiz to this thing ? I have one wire from the ground to the C, and one from the 5v to the L+ and then tried a few combos with no result, so I'm sucking it up and asking here

(I'm also pretty sure it's a 5v led, not a 12v)
