[sdiy] Keyboard springs?

[Rainer Buchty]

Hi everyone,

I got an ESQ1 which has been severely beaten up... I never saw anything
similar before.

Where the electronics are happy now after being freed from gunk on a
beer/ashes basis, the keyboard itself still isn't. For whatever reason,
traces on the keyboard pcb have been vaporized and in a more or less
futile attempt to repair them the previous owner killed a fair amount of
the contact springs.

The keyboard mechanics are rather cheesy: the col signal is fed through a
diode which is connected to a spring. Depending on the key position either
this spring makes contact to either the "up" or the "down" row:

              /o--- col_up#
row ---|>|---o
               o--- col_dn#

Now the question is, where would I get a bunch (well, make that 61) of
these springs? The "spring body" is 1.5" in length with a 2/16" "mounting
nose" where the spring just goes wider in diameter to fit into the key
clip (the other end is just soldered to a pin on the PCB).
