METHOD FOR CLEANING ELECTRICAL CONTACTS OF AN ELECTRICAL SWITCHING DEVICE AND MOTOR VEHICLE

The invention relates to a method for cleaning electrical contacts (11) of an electrical switching device (1), wherein at least one electrical contact (11) is cleaned, which has at least a first contact element (13) and at least a second contact element (15), wherein the contact elements (13,15) are displaceable relative to one another into an open position and into a closed position, wherein the first contact element (13) and the second contact element (15) are arranged in the closed position, and wherein the first contact element (13) and the second contact element (15) are excited to mechanical vibrations relative to one another in the closed position by applying an electrical waveform to the electrical contact (11).
