Buckling springs: CAN-5001CW

Unread post by Kurk » 26 Feb 2012, 13:23

I picked up this CAN-5001CW keyboard with an integrated calculator. The box says "mechanical feeling" which is the same as a sticker saying "duck flavor" on a pack of cheap, chinese soup. I popped off a keycap and to my surprise there was a spring underneath! So far, I only knew of IBM, Brother and Alps buckling spring switches. My initial enthousiasm quickly faded away when trying the keys: the ones at the outer regions of the keyboards (like A and Num-) are clicky and tactile but the keys toward the center do not click but feel rather mushy. The inside of the keyboard looks OK in a mechanical sense, the plastic is not warped so that should not be the reason for the lack of clickyness at the center.
The spring-and-hammer assemblies can be taken out of their barrels from the top. They are literally drenched in oil; at least they do not squeak.
Oh, and the whole thing doesn't work :cry: - hopefully I just need to replace the NiMH rechargable battery to get it going.

it is a Ya Sheng buckling spring...generally considered a horrible copy of the IBM BS. Someone here poured ligher fluid over theirs and burned it for our pleasure. Pics are somewhere, I've lost the link.

Mmmh, burning it, surely a thing to consider. There's so much oil on the switches that you won't even need the lighter fluid :twisted:

Just don't burn it while it's on your desk...

I was well aware of that, thank you. ;) It went up in smoke and made a mess, which was my point.

Why exactly are these so terrible?

Looking at the mechanisms, I can take a guess:

These guys make Model M hammers look like mighty Model F flippers!

Certainly fits with my theory: more flipper = more feel.

I think you are right on that muirium! I wonder what the Ya Sheng keyboards sound like?
