Method for cleaning electrical contacts of an electrical switching device and motor vehicle

The invention relates to a method for cleaning electrical contacts of an electrical switching device. At least one electrical contact (11) is cleaned, and the electrical contacts include at least one first electrical contact element (13) and at least one second electrical contact element (15) which can move to an open position and a closed position relative to each other; and when the first and second electrical contact elements are in the closed position, applying a waveform to the electrical contact so that the first contact element and the second contact element are excited to undergo a mechanical vibration relative to each other. 本发明涉及种用于清洁电开关设备(1)的电触头(11)的方法，其中清洁至少个电触头(11)，所述电触头具有至少个第触头元件(13)和至少个第二触头元件(15)，其中所述触头元件(13、15)相对于彼此能够移动到打开位置和闭合位置中，其中第触头元件(13)和第二触头元件(15)布置在闭合位置中，以及其中在闭合位置中，通过施加电波形至电触头(11)而激励第触头元件(13)和第二触头元件(15)相对于彼此产生机械振动。
