Consider the paths of the ground and break them up. Why? I have 4 buttons for quick coin adds on my cabinet. But I also have the coin doors hooked up.
I added a switch that broke the ground for the buttons when I want people (my kids) to use the coin doors. So with one switch I disabled 4 buttons (the grounds for 4 buttons since they are daisy chained) but allowed all the other buttons to function. I also have a cutoff switch for all of them. This is useful when I dont' want the kids to play at all, or if I'm running another keyboard/monitor off the back and don't want the kids adding keystrokes when I type.
