I got this from a my friend's storeroom
It looks like some mechanical switch over rubber dome, but I cannot find a lot of info about this keyboard, which use AT connectors. I found out the brand name is "Legend" and that's about it. Can anyone help?

EDIT: I disassembled the keyboard and it seems it a plunger thing over a whole sheet of rubber dome with metal back plates. This is a helluva rubber dome keyboard with double shot keycaps(?), 1 plastic plate, 1 metal back plate.

I opened it all up, there's no PCB except a the controller circuit PCB
The matrix are just a thin plastic film you find in cheap rubber domes.
The structure is roughly like this
Keycap
|
plunger
|
membrane
|
film
|
metal plate
No springs. I had it thoroughly cleaned, only to find out that it was not really nice to type on. My cheapo logitech feels better than it.

Sounds like old-rubber-dome effect.

Looks like rubber dome with sliders that allow them to use ALPS compatible keycaps.

Well the keys look double-shot, I figured it might worth the trouble of cleaning it or something.

They are truly paper thin. I broke one key while trying the remove the stabilizer/white plastic thingy on the keys with a screwdriver. It did not seem like a bad idea until the thing broke.
Anyway I am curious, are rubber domes with double shots a dime a dozen in the old days?
