First pachinko machine, so of course I have questions

Yes, I have seen flicker from the brass strips continuing to move after the payoff action is over even with the original switch parts. The strips are longer than many of the others I've seen, and they have a very skinny middle section. (which I duplicated).
I'm experimenting with adjustments now, with a next idea of putting a small block of closed cell foam with slits for the leaves in it as a damper to prevent the wobbling.

Have you (or anyone else) tried mounting a piece of rubber next to the leaf on the right, to prevent it from moving when the two make contact?

I'm thinking of trying it, wanted to see if someone has done it before.

I ended up getting it to work without anything to dampen the leaf motion. A lot of minor adjustments, but I ended up bending the contact areas closer to the (left) side where the seesaw first makes contact. I was going to the right at first and it didn't work.
Interestingly, my adjustments didn't seem to make it work reliably until I upgraded the voltage from 9V to 12V. Once at 12V it worked great for what that is worth.
