This unknown keyboard has the very rare Futaba sealed linear switch if I guessed right.
I clean this keycaps month ago but I desoldered the switches today. Will clean it tonight and next day.
The keyboard was made in 1984. All white variant. It also has the latching lock. Who can identify it?
P.S. The PCB drifting the dirty acidity smell when I was deslodering. I hope it not to be a sort of the poison gas.....



Latching Lock


same keyboard but Hong Kong or Taiwan layout

HatTa's owned(top one): (Linear)White with black shell

My Televideo Model 950 uses these. Springs seem pretty stiff to me, probably the stiffest I've encountered on a keyboard switch of any type. Feels like you are getting a workout just pressing one key down

As I researched my keyboard is not like the televideo905 keyboard. And the model 905 keyboard using the Futaba complicated linear switch. Not this Futaba sealed linear.
