I have a Fathom with pretty significant arcing on the EOS switch contacts. Is this normal?

The game currently has what I believe are low-current switch contacts for EOS and due to the arcing I am seeing some significant pitting and material transfer between the contacts. This has started to cause intermittent problems with dead flippers.

Should I install high current (tungsten) switch contacts instead?

What about capacitors? I've tried installing capacitors before but it didn't seem to help, and also caused other problems like false triggers on switch inputs. Has anyone managed to tame the arcing?

The game has a mix of old and new flipper coils. All three are marked AQ-25-500 34-4500. The flippers are the original linear style.

There's 2 sets of contacts in the photo. These are for the lower (main) right flipper. I believe the left set of contacts (the closed contacts) are the trigger for the upper right flipper. This is the only flipper that has a 2nd set of contacts like that. They are definitely high current (tungsten) contacts.

The right set of contacts (the contacts that are open to show the damage) are the EOS contacts for this flipper. They look like lighter duty contacts to me but I'm not totally sure what they are. They are the ones that have been damaged by the arcing.

Thanks for all for the info and advice. Just to be clear, the EOS switches should all be high current (tungsten) contacts, correct? If some of them are not high current that might explain the rapid wear, right?

I just found the receipt for the last time I ordered switches. The EOS switches are from Marco.

I can't tell if these are low current or high current contacts.

Marco is saying that both sets of contacts are tungsten, but the contacts on the left look considerably thicker. Is it possible that the contacts on the right are tungsten as well, despite being thinner?

I've got some of the thicker tungsten contacts from pbresource and I am tempted to replace the EOS contacts with those. Has anyone done this?
