blueboy:
Hi,
Thanks for answering a newb question...
I have this pushbutton

Which side is the ground for the led?
I know the configurations for the button itself.
Thanks again,
Blue

The shorter leg of the LED is the cathode:

Is that the right link? That's a lamp, not an LED.
blueboy:
Hmm..dunno why it linked there.
It's part 57-0004-41
Looks like both sides are the same though?
Any help
THanks,
Blue

If it's a drop in replacement and you get the correct voltage, then you shouldn't have any problems just trying it out in both directions (only the correct way will light up).
