Coin Switch connection for Midway Door

[DLO]

I'm trying to connect the original coin door switch to my iPac but have no idea which connection is the "NC", "NO", and the common ground ("CO").  If any one knows please help.  Thanks.

Take the switch off the door and flip it over. You'll see the markings on the switch: N.C., N.O., Com.

After investing so many hours into these arcades, it is sometimes easy to overlook common sense.  I removed them and they are clearly marked, I feel like an idiot.   THANKS KEN

And for other's reference.

Simply take an digital multimeter (one of those $3.99 Harbor Freight specials), set it on the diode testing setting (in the low ohm area--I think 200 ohm), then proceed to test the switch in the following method:

Touch:
Left+Middle
Left+Right
Middle+Right

While touching, press the switch down and release it.

If the display shows 1xxx ("infinate resistance") with the switch up or down, then the two terminals are the NO (normally open) and the NC (normally closed), and the remaining, untouched terminal is the CO (Common/ground)

If the display shows 1xxx with the switch up and 0 (or close to 0) with the switch down, then the terminal that isn't ground is NO.

If the display shows 0 with the switch up and 1xxx with the switch down, then the terminal that isn't ground is NC.

another good way would have been to use the two places it had already been soldered.
