I want to use one of my leaf buttons from my original Galaga machine on a jamma harness. Do I wire the two positive wires to the single positive wire on the jamma harness?
-
Wire one connector to common ground on the harness and the other to your positive connection for the button on the harness.

On the leaf switch, there are two wires on the positive terminal and one wire on the negative terminal. I wired both the positives to the positive wire that was on the microswitch and the other to the common ground. It is not working. Any suggestions?

if youre replacing a switch with another type of switch, wire it the same, same wires connected each side. Not exactly sure of what youre asking :-\

Once you remove the 2 wires from the microswitch, you need to solder the ground wire to one connector and the positive wire to the other connector. It really doesn't matter which wire you connect to each connector on a leaf switch, since the way they work is when the two wires contact each other it will issue a button press signal. To demonstrate, remove the wires from the microswitch and then touch the two wires together. The button should trigger a "fire" on your Galaga ship in the game. The leaf switch (the long metal pieces, simulate what you are doing - closing the circuit).
(see pic below - you should connect the wires to the shorter connectors).

Thanks everyone, I got it figured out. They had two wires on one terminal and one wire on the other terminal. The two wires were yellow and the single wire was black. The black was the positive lead and the two yellow wires were grounds. I had it wired backwards. Duh.... Lesson learned, never trust the color of the cables on an old machine from 1981 :cheers:
Man, I wish I would have put a leaf in from the beginning. Now I can fire the way I used to in Galaga.

glad you got it sorted, still not sure what you were actually stuck on, switches dont have polarity issues...... still at least you learned how to move cables :)
