Honeywell Micro-Switch KB—what are these?

[ander]

This just appeared on eBay:

HONEYWELL MICRO SWITCH KEYBOARD SW - 12534 CPS - USA MADE /// NEW!!!





I'm not posting it in Great Finds, as it's $200 OBO (which may be a great find, but I don't know). I was wondering: Are those Hall Effect switches, or what? And are a bunch of caps missing, even though it's being offered as "new"?

They look very much like Honeywell dual magnet Hall effect to me. Supposedly they're the best of the best .

Here's another ($450 OBO):

NEW Honeywell 101SW1-4-H Keyboard PLC Board 101SW14 101SW14H SW-12559 SW12559 2

Whereas I believe this one ($50) would be RD (though still nice looking!):

Honeywell Engineer Keyboard 51196712-200






And here's one more interesting one ($589 OBO—so you can see why I'm not doing this is Great Finds):

Honeywell Operator Keyboard 51400989-400 L 51400821-100 Engineers KYBD





(I've rotated and re-angled the seller's photo)

I've got one of these on the way. New, $120 shipped.

I worried a lot about if they were legitimate old school HE (I did't see this thread until just now) - in my search for information, I found a supplier that still had one lying around, they wanted $2100 Really makes me wonder what these switches went for back in the day.

Wonder if anyone's got a HE keyboard to work on a modern computer.
