Quoted from frunch:
They're used to help particular switches sense quick closures. Some switches may seem intermittent or unresponsive without the cap installed. Most of the time i see them on rollover switches and standing targets. I wouldn't add them to switches that don't have them unless i exhausted every other solution. Have you tried cleaning and adjusting the switches you're having trouble with?
appreciate the response, I'm not having any issues. I was just comparing one of the newer MPU-200 sterns to this older one. Seems like they always used them on the slings and spinners. But then randomly placed them on other targets around the game. Mainly just trying to understand the reason behind it. Was it because a whole row or column that benefits from one switch cap (wired in series) ? or was a there a reason they chose that specific switch. I understand their purpose, which is why I was gonna put them on the slings and spinners of this game. Since they have faster hitting switches.
Started replacing them on my last game, its the only reason I thought to look at placement this time. Remember someone suggesting it as a good idea to replace them, and they brought valid points as to why.
