Switch contacts should be free of dust. dirt. and corrosion. Filing or
burnishing most switch contacts breaks the finish and encourages
corrosion. Effective contact cleaning requires gentler treatment. Gently
close the contacts on a clean business card or piece of paper. Wipe the
contacts until they're clean. If necessary. regap the contacts to 1/16 inch.
