That’s a lot of non-working keys. Supposedly the contacts of the Datanetics switches are sealed and there’s no way to clean them. Might have to desolder one and try it anyway.pic.twitter.com/U5iOWx3ono

Pulled the ESC key to see what can be done.pic.twitter.com/JimHlOWxAJ
Switch is definitely not making contact. The two terminals inside are supposed to be sealed between layers of Mylar. What happens if I spray contact cleaner up the leads?pic.twitter.com/9ezE5tPckG
It works! The switch is making contact!pic.twitter.com/aueV18xNIl
Had to try it again a couple more times to verify it works. It sure does! Sealed my ass! The two halves might be glued together but the contacts aren't sealed. Datanetics DC-51 switches on Apple II keyboards can be revived!pic.twitter.com/cxHDNUzZ3s
And all the keys work! Some are a little bouncy but should get better with use. Two keys were more stubborn than the others but I just kept repeating the contact cleaner and they started working.pic.twitter.com/uAtJZZqYMj
