Is there a way to determine what type of switch a particular Ajazz Geek AK33 uses by reading the barcode on the back of the unit:

Briefly, I need to replace a black switch (i.e.
non-clicky) AK33 that has a defaced (hence no helpful barcode) label.
Unfortunately, the people flogging used ones (all I can find) seem to know even less about keyboards than I do.* While I suspect I may be on the wrong track with the barcode, I am hoping there is
some sort of "tell" on these keyboards that reveals what keyswitches are installed on a particular unit at a glance.
Can anyone help?
(And yes, I know: I can always ask a seller to prise off a keycap and take a photo. However, I am seeking some way to quickly eliminate the clicky ones without having to pester every seller of every Ajazz I see.)
Alternatively, if anyone knows of a source for new, non-clicky units, I am all ears. It isn't much fun playing guessing games with the people offering used ones, but as I say, used ones are all I can seem to find.
*Which I did not think was possible, but there you are.
