My understanding is these were custom keytops ordered as part of the 'low cost
keyboard' article that appeared in RE. According to RE, the keyboard on the cover
unit was built using the method Don described, including hand made (and very laboriously
made) switches. Definitely not microswitch as far as I've read.

These are late 60s Micro Switch modular keys. I believe that the tops attach to the keys
