Abstract
A method for cleaning electrical contacts of an electrical switching device includes displacing a first electrical contact element and a second electrical contact element of an electrical contact relative to each other so that the first electrical contact element and the second electrical contact element are in a closed position; and when the first and second electrical contact elements are in the closed position applying a waveform on 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.

A method for cleaning electrical contacts of an electrical switching device, said method comprising:
- displacing a first electrical contact element and a second electrical contact element of an electrical contact relative to each other so that the first electrical contact element and the second electrical contact element are in a closed position;
- and
- when the first and second electrical contact elements are in the closed position, applying an electrical waveform using a control device so that the first contact element and the second contact element are excited to undergo a mechanical vibration relative to each other without leaving the closed position.
A motor vehicle, comprising:
- an electrical switching device, said electrical switching device including an electrical contact, said electrical contact having a first electrical contact element and a second electrical contact element, said first and second electrical contact element being displaceable relative to each other between an open position and a closed position;
- and
- a control device configured to apply an electrical waveform on the electrical contact when the when the first and second electrical contact elements are in the closed position so that the first contact element and the second contact element are excited to undergo a mechanical vibration relative to each other without leaving the closed position.
