Abstract

An electric switching device for achieving a rapid simultaneous electric closing of at least three conductors (13) intended for high current and high voltage. The switching device comprises a container (3) which is limited by two plates (1, 2) and a cylindrical casing (4). The container (3) is filled with gaseous insulating medium and encloses an electrically insulating fire tube (7). Insulators (6) are connected to the casing (4), through which insulators the conductors (13) are connected to contacts (17) arranged in the fire tube (7). A missile (10) of conductive material rests at one end of the fire tube (7) and a damping block (11) is arranged at the other end thereof. By the compressive force from an explosive charge (20), the missile assumes a contact position in which it is wedged in between the contacts (17).
