I have a Playmatic machine that had a small metal tab break off and I can't find a replacement Playmatic part, however I know nothing about EM machines and this might be a standard part on EM machines. Pictures are attached, I will describe it to the best of my abilities.
The machine has "dip switch settings" to control things like number of balls. There is a small piece of metal that is shaped like a screw with a wire attached that gets inserted into one of five slots. Each slot has a small metal tab on the outside, somewhat like the metal tab that makes contact with a "AA" battery. While moving the "metal screw" from one hole to the next, the metal tab broke off for the 5 ball setting. Is the a common part? Is it repairable at all?
