So I'd always passed over these keyboards thinking "probably just another dome...". But was I so wrong. I have 3 keyboards that look very similar, all with different switches. I suspect Burroughs/Unisys possibly used even more OEMs.
This one uses ITW Low-profile magnetic valve switches. And for those unaware, Cortron (used to be Licon) is a subsidiary of ITW.
Excuse some of the grime, I tried my best to clean it off...
Very nice! These switches have a very interesting operating mechanism. Btw, the keycap shape is a dead giveaway for them . Very nice pictures, thanks for posting them! Looks like Burroughs had quite a variety of interesting mechanical switches xD .
Interesting layout also, with the XT style function row on the left and that nav cluster at the top right. It's also got german "TÜV Rheinland" and "GS" quality certification stickers.
