push button contacts fail Answered
i disassembled my full-automated coffeemachine as the push buttons for programs failed. The buttons are a line of rubber and the contacts on the platine are toothed while each rubber contact got tiny plates that bridge the contacts on the platine. I guess that the contact plates lack of conductivity - any suggestions what i can do to improve the conductivity? I thought bout buying contact foil and glue it over the rubber contacts, but i don't know, if this is the best solution.
