Could you post a picture of your Meteor switch ? People might be able to guide you if they don't have a Stern pin of that era to check.

LTG : )

Is that a high power switch ( kind of direct drive like a flipper EOS ) ? If so a low power Williams switch won't work.

If it's low power like Williams DMD era pop bumpers, then a Williams switch will work fine.

I ask because in your picture the contacts look a little burned like high power.

Those are low power switches, as they run through the "switch matrix". They're not the direct switches.

You don't need to replace the switch, unless something is very wrong with it. Just clean up the contacts.

You'll need to replace the spoons. The holes on the new spoons will need to be enlarged to fit the switch stack. I use a step bit in the drill press, and slowly press the spoon base into the bit.

Pic number two tells me the switch has been hacked. Stern didn’t use wood screws like that to mount a switch.
It looks like someone has put a high power switch, like a flipper switch, in place of a low power gold plated switch.
What do the others look like?

Those aren’t wood screws. If you look at the tip of the screw, you’ll see that it’s flat, not pointed.

These screws go into tinman nuts on the underside, that you can’t see.

The screws shown are most likely factory.

You can probably use either of these two switch assemblies:
