Correct relay to use with KeyWiz
DaOld Man:
A optoisolator would work just like monmotha suggested, but may be simpler than the transistor.
Either circuit would be a lot cheaper than a relay, and be less energy using and no "clicky noise."

I was just going with a relay because I thought it would be easier but as this is all new to me I am not sure which way would be easier :). I would like to use this same swipe card device on my other cabs such as my Golden Tee. I figured it would be fun to log when people play what game and maybe have my nieces and nephews playtime controlled a bit. But of course the main reason to do this is to have a little fun hacking something together and learn a few things along the way :).
So I guess my question is which of these options would work to close the circuit on a coin input on a regular cab just like the little micro switch is currently doing when the coin is inserted. If I don't need to order to much I would prefer to get the stuff from radio shack to save on the shipping but either way I appreciate the input.

I'm not sure if Im getting the full picture here, but I think any of the mentioned methods would work, but the relay BobA suggested would probably be the simplest.

I just posted my last post to fill in what I was doing a little more I didn't want to end up using a solution that would only work with the keywiz, but would also work with any original arcade pcb. I just want my solution to bridge the wires that are connected to the switch that is used to credit a game when the coin comes through. I am very new to this stuff but I am trying to understand what I can. I am having a hard time following exactly what parts I will need for each solution.

Is this all I would need?
I would also like to know what parts I would need for the transistor and the optoisolator solutions.
Thanks again for your time.

Here is a quick circuit using a TIL119 optoisolator and a 300 ohm resistor.
Radio shack probably wont have the optoisolator, but you can search the web for a dealer.
Or pm me your address and I will give you a couple of them. I bought several on ebay back a couple of years ago when I was experimenting with my rotating monitor circuit.
