When I built a single level paddle, I decided to use silver for
the contacts after hearing that all the corrosion products of
silver were conductive. I soldered two short pieces of silver
wire, contributed by a jewelry maker in the family, at right
angles to each other on the contact bases.
In spite of mostly sitting on the shelf for five or so years,
presumably corroding, this system still works quite reliably. I
have recently been using it with a Rockmite, and it shows no
signs of intermittency.

Using a favourite pre-war Morse key on vintage valve gear, it
worked perfectly, but on modern solid state equipment it was
very intermittent and I didn't want to make an interface.
Solution, clean the contacts. Conclusion: modern gear needs
better contacts than the old stuff.
