Abstract
The invention relates to a compressed gas switch with two contact pieces, a contact element by-passing the contact pieces when in the on position, and two isolating distances connected to each other in series. The second contact piece opposing the first isolating distance is arranged axially by an annular piston to be displaceable forming a switching chamber. The switching chamber is separated from the heating chamber by a bulkhead partition having a current-dependent valve, and the second isolating distance is produced after opening of a blowing hole located between the second contact piece and the contact element.
