Quoted from MutterFudder:
My cabinet also had pilot holes were a normal switch would go. I just used those.
Use a single contact instead of a double. Cut the diode off. https://www.pinballlife.com/stern-flipper-leaf-switch-single-contact.html
Edited to add if you already have a double contact switch just use one of the contact pairs.
So you switched to Stern switches?
If so, would you say there is a significant difference in the way the game feels? I would assume with the extra blades for tension, it will feel much better than the cheapo factory switches.
