KBK update for Friday, 27th March

Although a few Raytheon keyboards are known, it appears that there is only one discovered example made by Raytheon themselves, using reed switches (the others were made by Cortron). Meryl Miller collected a sample switch at the end of the 70s or early 1980s that appears to be Raytheon — I could have had it and would have had it if I had realised it was a keyboard switch (likewise his Fujitsu FES-2 and Micro Switch 1PB870 and KB types).

A new Raytheon page collects together what little is known about Raytheon’s keyboards and switches, including a single photo of Meryl’s type and a diagram showing how it appears to work, based on his photograph and a patent for an older design.
