Abstract: An electrical switching device including at least a nominal contact arrangement, the nominal contact arrangement at least a first nominal contact with a plurality of nominal contact fingers forming a finger cage concentric with respect to a longitudinal axis (z), and at least a mating second nominal contact. An arcing contact arrangement including a first arcing contact and a mating second arcing contact. An arcing contact finger including at its free end a first impact area in which a first contacting to the second arcing contact occurs when closing, the electrical switching device. The first impact area is formed by a first planar surface arranged at an inclination angle (α) larger than zero degrees with respect to the longitudinal axis (z).

Abstract: An electrical switching device for medium or high voltage circuits having at least a nominal contact arrangement, wherein the nominal contact arrangement includes at least a first nominal contact including a plurality of contact fingers forming a finger cage concentric with respect to a longitudinal axis, wherein the contact fingers are separated from one another by empty slots extending up to a free end of the contact fingers. The empty slots include first and second empty slots, wherein the second empty slots are shorter than the first empty slots, and wherein the contact fingers are grouped in groups, with the contact fingers of each group being separated by second empty slots and the contact fingers of adjacent groups being separated by first empty slots.

Abstract: A contact arrangement has a longitudinal axis and includes a first contact group with a first contact and a second contact and a second contact group with a third contact and a fourth contact. The first contact interacts electrically and mechanically with the third contact, and/or the second contact interacts electrically and mechanically with the fourth contact, for closing and opening the contact arrangement. At least one mechanical coupling is provided for transmitting an actuation force to the second contact group and thereby moving the second contact group. The at least one mechanical coupling is adapted to move the third and the fourth contact in such a way that their speeds differ along at least a portion of a travel path of the third contact or along at least a portion of a travel path of the fourth contact.
