A contact arrangement has a longitudinal axis (z) and comprises at least a first contact (4a) and at least a second contact (4b) interacting electrically and mechanically with each other for closing and opening the contact arrangement. The first contact (4a) is surrounded by a protecting cover element (2) in such a way that a contacting extremity of the first contact (4a) protrudes beyond the cover element (2). The first contact (4a) and the cover element (2) are arranged with respect to one another in such a way that a gap (7) is provided between them along at least a portion of their elongation, wherein the gap (7) has a first opening (10) towards a first volume (15) surrounding the first contact (4a). The cover element (2) comprises at least one chamber (9) connected at least to the gap (2).
