I noted on their website they have replacement bandswitches for the Kenwood TL922
I noticed that too. Multi-Tech will make anything to order. From http://www.multi-tech-industries.com/rswitches.html, "All switches are custom made to our customers' specifications." Since custom = expensive, the question is how bad you want it.
The best alternative is a switch from a donor amplifier. In that case for the OP's amplifier, the resources I previously listed are likely the best:
What a project for a guy with some mini-rivets, a sheet of thin spring-tempered brass stock, a rotary tool, and a steady hand...
You don't even need to make the switch contacts . . . they are the same as on lots of ceramic wafer switches, which you can buy cheap on Ebay..
All you need to do is buy some and swap the contacts onto your FL2100Z switch . . . it really isn't that hard.
Contacted them, but they do not make a FL-2100Z bandswitch.
However a friend of mine is giving it a go, he restores old army radios and hopes to be able to repair/replace the wavers.
You might try The Radio Shop, You tube video #40, Wafer switch repair. Also part 19, more on repairing wafer switches-you tube. Good luck.
Thanks but his video is about cleaning, mine has melted contacts.
I wish it was only cleaning, but I need new rotary and contacts, in short new wavers.
Thanks for the video, could be helpful some other time.
Really need replacement parts.
Gotta love those prices!!
Finally some progress,
I contacted Keiichiro Kubodera / JA1IIV, he has a company in Japan that makes bandswitches.
He is so kind to send me replacement parts to repair the switch myself!!
Now I have to wait and see what he ships me, but at least somebody from a company that answers and tries to help.
I've used 2-56 screws/nuts rather than rivets - less chance of breaking the wafer, just don't over tighten and use a little locktite to keep the nut tight.
