On many pinball machines like early solid state Bally and Stern games, you’ll often see little capacitors on most of the playfield switches. Sometimes they’re there but a leg is cut off. Why are they there? What do they do? And are they important? We’ll talk about that.

What are these capacitors? Originally they were 0.047 uf 50v. There are various versions you can use. I will sometimes replace them with a 0.1uf and it works fine.
Any .05 or .047 uf at 50 volts or higher mylar or ceramic disc type is fine. Here’s a sample link: https://www.newark.com/vishay/1c10z5u473m050b/cap-0-047-f-50v-20-z5u/dp/57AC4650?st=0.047uf
