Advice on properly wiring an illuminated switch
shawnzilla:
Can anyone advise me on how to wire this pushbutton switch?

I have successfully wired it so that the switch itself works for turning on and off my device, but I can't figure out how to get the led inside of the switch to illuminate. The switch itself has three prongs.
Rawker:
just tie the commons together, hook up the blacks to the switch (order doesn't matter but usually source on the bottom) and then hook up the ground to the switch which will allow it to illuminate.

I guess I'm still a little confused:
I am trying to create an on/off switch for an led (to go under my trackball), powered by a 9v battery.
I have already gotten the on/off action to work by going from the battery's positive terminal to one of the bottom prongs. Then I wired the other bottom prong to the LED's positive terminal (through a resistor, of course). Then, I've gone straight from the battery's negative terminal to the negative terminal on the led.
Even if I wire the negative terminal to the third (side) prong of the switch, the light on the switch does not illuminate (although the on/off action of the led still works). What am I doing wrong?
thanks
Rawker:
ground the 3rd prong, the ground will illuminate the switch when in the off position.
shawnzilla:
Isn't the negative terminal on the battery considered to be the ground? If so, then the switch still isn't lighting when hooked up.
