There is a threshold voltage for metal-to-metal contacts made of oxides of
tin, and it is higher than 5 volts... hence the poor performance record of
tin-only connections @ 5 volts or below. There are many good connectors
available that have gold (or nickel) contacts available and I would advise
anyone to use nothing less-again: when dealing with low current, low
voltage, signal level voltages.
