I fixed a 'pocket dictionary' thing for my dad. It uses about 30
conductive rubber buttons which had worn out.

I used a black plastic anti-static bag, the sort which electronic
components or assemblies are often kept in. (Or were - nowadays it
seems that a transparent plastic is more often used, and I don't know if
that would work.)

I cut this up into short strips and glued them onto each rubber pad with
a smear of RTV silicone.

Worked a treat.
