I just received my Ultimarc buttons for my control panel and the NO NC and Common contacts are not labeled. I know which is Common but which contact is NO and which is NC? I know that on my J-Stick joystick, the middle one is NO and on my coin door NO is the outer one. I'm assuming that they're the same as the joystick where the middle contact is NO but if someone could verify this I'd appreciate it. Thanks.

Use a multimeter if you have one and do a ohms test or use the buzzer to see.

on my Happs stuff its like so
-----NC
-----NO

|---- (ground)
and i beleive ultimarcs are the opposite..
hope that makes sense..

I was going to try a multi-meter but mine is dead :'( So I was just wondering if anyone had these buttons that maybe knew the arrangement.

Get a light bulb. A 12VDC car bulb will do. Connect the battery negative directly to the bulb..
Connect the postive from a battery to the microswitch common. Then connect one of the NO/NC contacts from the microswitch to the positive on the light bulb. Which one needs switching? ;D
-
Here's a suggestion on how to do it, assuming you have a coin door:
- wire the switch to the bulbs of the coin door and then power it ... should act as a multimeter ... ;D

The switches I got from Ultimarc were Cherry brand.
If you're looking at that switch from the side, the very bottom offset lug is the common and the next one above is the NO. Top is the NC.

The switches I have are Cherry Brand also. Thanks a bunch.

You must really want an answer, you posted this on a few different boards.

Why didn't you just try it out, and if it didn't work, move it?

Well I was working on it late last night and was going to test it w/ a multimeter, which was found to be dead. So I figured I'd find out while I was at work today, rather than disconnecting my bulbs from my coin door to try it out and rather than hooking up the IPAC and going through the setup. The connectors are EXTREMELY hard to pull off of the contacts on the switches(why I didn't want to have to move them around). Just figured it'd be easier than playing around with it for a couple hours.

Um... perhaps I am missing something here, but why don't you just hook it up to your encoder and find out what it does? If the button is constantly sending the "ENTER" (or whatever key) then you know you hooked it up to the wrong connection...

As stated before, it was getting late last night so i figured I'd ask while i was at work. I don't have my computer completely hooked up yet so i couldn't test it w/ the IPAC.
