Good morning!

I'm the proud new owner of four low profile Atari "volcano" buttons.

After further review, I found that the contacts are labeled NC and NO, but there are two of each. Hummmm

Standard diode drops voltage by 0.7V.

I asked that same question a while ago...

I seem to recall that two of the terminals under the switch are 90 degrees different from the other ones.  Those two are the light source.  You can test the LED with a couple of AA batteries.  Just don't leave 3V hooked to it for too long.  5V from your IPAC without any resistors will make the LED burn really bright for about 15 seconds and then pop and stink.

Do not use AC!
