Ultimarc Buttons (Which is NO ?)

Pages: (1/3) > >>

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.

Craig:

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

SOAPboy:

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.

Craig:

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
