Multiple wirings for one button?
« on: March 02, 2007, 01:17:26 am »
I have a 1 player and player start button on my machine on the far left and far right, however there are also places for them in the middle of the panel.

Is there a way to wire both of these buttons to work at the same time?  If I wire them similarly to a ground loop wire, will both function as start buttons?  I don't see any reasons why it wouldn't work, but it's good to know for sure if someone does.

I know that Y adapters exist to allow a button to be plugged into 2 boards at once so swapping games is easier, but can 2 buttons be hooked up to the same board via the same wire?

Yes you can do that.

The way that the button triggers the encoder is by closing the circuit between the key that you are using for player1 and the ground.

In order for this to work you need to make it so that whichever button is pressed, that circuit gets closed.

If you wire from your encoder to one of the buttons like you normaly would and then run wires from the contacts on the switch to the same contacts on the second switch you should be set to go. 

You are wiring them in parallel, so that if either button gets pressed, it closes the circuit and sends the signal.

I hope this helps, if I ramble it is because I am dozing off.

Later,
Brian

Yea, thats what I was thinking, it will be another loop such as the ground loop works, but instead of being ground it is an actual trigger circuit wire.

Thanks for the info.
