Does anybody know if the IBM 4704 Bank Terminal Keyboard is buckling spring?

Here's a picture of it:

It's quite possibly beam spring, even more arcane...  Haven't found much about it online, but here's an abbreviated IBM chronology that mentions it being new in 1981.

I hadn't even considered that it might be beam spring!

I like the 50 key grid format. I may just risk it and buy it: just to see what it is...

It's way too low profile to be a beam spring. Must be Buckling Spring or some rubber dome.
