My Fireball machine came with 1 orange button and 1 yellow button. Both very old and dirty, so needed to be replaced. I wanted to swap them out with new red buttons (to match the red credit lamp and red t-moulding). Brand new flipper switches were installed, along with the buttons. I had a bit of an issue tracking down the correct size buttons.
The yellow button shown is what was in the machine originally, while the two different red buttons came from a parts supplier. You can see one is too long while the other is too short. The problem with the too long button is it pushed the right flipper switch out too far and connected with the shooter rod. The too short button couldn’t get enough thread through the side panel to attach it.
I was able to source the correct button from a supplier by giving them the above photo. So finally, I have new flipper buttons. I thought swapping them out was going to be quick and easy – never assume I guess 😉
