Abstract
Electrical contact system with a first and a second contact (), each having a contact surface (). The first electric contact () has a mesostructured electric contact portion () with a plurality of slots () and ridges () formed between neighboring slots () of the plurality of slots (). These slots () and ridges () extend in a direction running transversely to said switching plane (X-Z) form a plurality of current paths (). The current paths () are inclined to the first contact surface () at a first angle () measuring less than 60 degrees such that an interruption current () flowing through the mesostructured electric contact portion () and through an electric arc () extending in between the first contact surface () after lifting the first contact surface () off the second contact surface () pushes said electric arc () in the direction of the apex of said first angle () from a first position () to a second position ().
