Abstract (en)

The electrical switching device (1) has at least a nominal contact arrangement, wherein the nominal contact arrangement comprises at least a first nominal contact comprising a plurality of contact fingers (3a) forming a finger cage concentric with respect to a longitudinal axis (z), and at least a mating second nominal contact (3b), wherein at least one of the nominal contacts (3a, 3b) is movable parallel to the longitudinal axis (z) and cooperates with the other nominal contact (3b, 3a) for closing and opening the electric switching device (1). The electrical switching device further comprises a supporting tube (6) fitted into the finger cage and contacting the contact fingers (3a). The supporting tube (6) carries a plurality of spacers (7), each of which extends into a gap between two adjacent contact fingers (3a).
