Simple button wiring question
DJMattB241:
So I bought LED buttons like the ones in the picture below. Now, I'm still relatively green to the whole wiring thing, so bear with me while I ask dumb questions like:
The LED part only has two connectors, I assume it doesn't matter which one is which?
The switch has three connectors. What's this all about? I thought it was one to the control board and one to ground. What's the third one? And which one is which?
Thanks guys/gals!
Nephasth:
The three terminals on the microswitches are COM (common, which should be connected to ground), NC (normally closed, which typically isn't used in arcade machine applications), and NO (normally open, which is the terminal you want to connect to your controller input).

Yes, it matters. LEDs have a positive and negative connections. You must wire them accordingly otherwise they won't work.

Paradise does sell non-polarity sensitive LEDs, but I don't know about the ones included with those particular buttons. Easy way to tell, if you have a multimeter with a diode function, put the red lead of the meter on one terminal of the LED and the black lead on the other. If it doesn't light the LED, swap leads. When it's lit, whatever terminal has the red lead on it is your positive terminal, the other is ground.

If that is the case, then I stand corrected.
