KBK update for Thursday, 5th November

A new page is posted on Data Interfaces, Inc. and their known keyboards, keypads and switches. They produced low-profile switches with dual pairs of gold-alloy crosspoint contacts connected in parallel, in a similar manner to Omron B3K. The switch contacts were separately enclosed for protection against foreign particles, just as some modern switches. No photos exist of either the keyboards or the switches, but the descriptions are clear enough that they may be sufficient to identify an unknown switch should one be found from the 1970s that matches.
