Question about the rou foam (felt?) pads protecting the switches on Sixers.

[Mef]

Recently got my first Sixer (Light, but the lid looks like from a Heavy, there's also a couple discrepancies here and there, but I'll post in relevant topic once I get the time to document it all). It was in a really bad shape and wore multiple signs of amateur tinkering. Lacking all of the original case screws and those circular black pads that protect the switches from dust.

 

What are these actually made of? I've heard people call them felt pads, but in Best Electronics catalogue I've read that these are foam pads.

Also, did anyone here replace these with homemade ones? If so, what kind of material works the best, any suggestions?

 

P.S. The "rou" in title was supposed to be "round" and was added at the last moment, didn't notice I ran out of available characters.

They look like thin foam to me. Many hobby stores sell foam sheets for cutting out letters and whatnot. You could probably find something there. If not, maybe McMaster Carr (mcmaster.com) has something that would work. Of course, if you're going to mail order anything, you might as well get the original ones.

Cheers. I did some more digging in the meantime and found a close-up pic of the original foam discs.

For my replacements, I used a 2mm black PVC foam (it was called Crea Soft), should be easy to find in hobby/craft stores if anyone else's looking for those.
