Switching device arrangement

摘要

The invention relates to a switching device arrangement comprising a first contact set (11) and a second contact set (12). Said first contact set (11) comprises a first electric arc contact element (15) and a first nominal current contact element (13). The first nominal current contact element (13) can be moved relative to the first electric arc contact element (15). A first transmission is introduced in a cinematic chain in order to generate a relative movement of the first nominal current contact element (13) and the first electric arc contact element (15). The first transmission is operationally connected between a stationary counter bearing (31, 33, 33a) and the first electric arc contact piece (15).
