here are a few images of the arcade button concept as quite often I notice kids at the arcade or even when I have visitors over who obviously have never played a pinball not sure how to rack up more than a one player game and even then the start button is not suggestive enough, so I was thinking a few player buttons as then kids will know which button to push to start. Currently just a 2 game setup but easy to add more.
also I wanted to build a cabinet to suit both a plunger and a launch button (like on AFM or MM) so I can quickly swap out parts and convert from one to the other without needing a new cabinet. So I designed a plug to insert into the plunger hole and have a lip on the inside outer edge. The launch button is 60mm dia so it covers the plunger hole and passes through the adaptor and then the launch button nut locks everything together.
