A 'el cheapo' method I saw in a Radio-Electronics column once was:
Use the conductive foam that your ICs come packaged in as the main
ingredient in a copper sandwich. A picture will help:
-------- <-copper disk (penny, PC board, whatever)
~~~~~~~~
~~~~~~~~ <-conductive foam
~~~~~~~~
-------- <-copper disk
Your wires are connected to the copper disk. When compressed, the
resistance of the conductive foam is reduced. You could easily
experiment to find values.
