So it's possible they may not be make before break,or they are but the contacts are too narrow and they don't catch another one before leaving the previous.That is a pity.

I would but I need 5 kohm.
10kohm might be too ,but 22 is too high for sure.

Bartek,

Peter and I mentioned one other possibility- That the contacts bounce when they are switched from one contact to another.

If I owned one I would experiment with bending the wipers. First to lower the spring pressure. If that didn't help, I would try bending t hem to increase the pressure. Perhaps someone could try this

I am not talking about the detents, but the contacts.
