Abstract
An electrical contacting interface includes a low and stable electrical transition resistance including at least two contacting partners, which interact for electrical contacting. According to an embodiment, in one of the two contacting partners, in the region of a contacting surface, a structure is formed which protrudes from the plane of the contacting surface of the one contacting partner. The structure deforms under the influence of a mechanical force and causes a corresponding deformation in the shape of a recess in the opposite contacting partner. The structure protruding from the plane is formed such that even after the deformation caused in the opposite contacting partner and the flat regions of the two contacting surfaces do not touch. Therefore, the electrical current is forced to flow solely through the contact interface created during the deformation process, such that the electricity transfer surfaces are precisely localized.
