Arcade button for use with micro switch

I wanted to make my own arcade buttons, I have access to lots of micro switches so I wanted to use those. The ones I used just press into the bottom and don't need glue. Depending on the length of the button on the micro switch you may need to file down the small shaft on the inner piece to get a good action, if it is too long you don't get enough "push" and it doesn't feel right. I used some 3/8"x5/8" springs I had in a kit to give the buttons some return. They work well, but you could probably use other springs. These buttons fit in about a 28mm hole.
