How to wire 2 buttons to 1 microswitch???

[newman117]

Hello fellow arcaders! I'm finishing my xbox coinops cab... problem is, coinops is programmed to exit games by pressing the coin button and player 1 start button. My question, how can I wire both buttons to just one button, or one microswitch??

Do you mean simultaneously pressing 2 buttons, to, in effect, trigger one "button press"?

Most Keyboard controllers (like the IPAC) have a "shift" function that allows you to do something like this.

If you really want to hardwire 2 buttons to trigger one "input", then you could wire Ground to one button, then NO from that button to GROUND of the second button, then NO from that button back to the input on the keyboard controller.

In that fashion, BOTH buttons would have to be pressed for a connection to be made and hence, a button press. But that doesn't seem like what you're looking for exactly.

Or you could use two diodes to simulate 1 button pressing two buttons.
This is taking for granted that the common on your keyboard emulator (input board) is ground, or negative.
If it is positive, just reverase the ploarity of two diodes.
