Electrical medium or high voltage switching device

摘要

The invention relates to an electrical switching device (1) for medium or high voltage circuits having at least a nominal contact arrangement, wherein the nominal contact arrangement comprises at least a first nominal contact comprising a plurality of contact fingers (6, 7) forming a finger cage concentric with respect to a longitudinal axis (z), wherein the contact fingers (6, 7) are separated from one another by empty slots (10, 8) extending up to a free end of the contact fingers (6, 7). The empty slots comprise first and second empty slots (10, 8), wherein the second empty slots (8) are shorter than the first empty slots (10), and wherein the contact fingers (6, 7) are grouped in groups (5), with the contact fingers (6, 7) of each group (5) being separated by second empty slots (8) and the contact fingers (6, 7) of adjacent groups (5) being separated by first empty slots (10).
