KBK update for Saturday, 19th September

A Cherry advertisement placed in Computer Design in September 1983 offers some unexpected features of the then-new MX series: double contact, double pole and angled plungers. Angled plungers are perfectly possible, but have never been observed. The patent depicts double pole, but this has also never been seen. Double contact is not defined precisely, and nothing matching this description has been seen either; the split movable contact design shown in the patent might be there to allow each side to flex separately, with its own contact prism.

Günter Murmann, the designer of the MX switch, implied that these options were produced, but fell out of favour over time. It is not clear what part numbers they would have had.
