First of all, a giant thank-you to Tony for getting it all right (from
memory, no less). Unfortunately, I still need advice:

positioned. Fit the base/PCB and slide it over to lock it. Don't bend the
tab yet. Prese the space bar down so it clicks in place, and check it
clicks and returns properly. If not, you need to take the baseplate off
again and have another go.
While this fixed the spacebar, it has rendered other keys unusable. I
have taken it completely apart and reassembled it three times now and no
matter what I do, the return key is dodgy (doesn't always register, or
registers twice) and the numeric "-" is dead. I have looked at the
surfaces, both on the board and the buckling spring assemblies, and
everything looks clean -- I can't see why I'm getting screwball key
behavior on a few keys. I've completely rearranged the buckling spring
assemblies (they are identical) so I'm not sure what else I can do...
any advice?
On a side note, how does this mechanism work? I understand how the
buckling spring mechanism works, but it looks like a piece of plastic is
hitting two metal pads -- since plastic doesn't conduct electricity, how
is this working at all?
