Abstract

A short-circuit switch for use with a first electrical conductor and a second electrical conductor includes a controllable semiconductor switch that is configured to short-circuit a voltage present between the first conductor and the second conductor responsive to receipt of a trigger, and a mechanical press-pack structure. The controllable semiconductor switch is a press-pack-type thyristor having a first planar electrode and a second planar electrode on contact sides situated opposite one another. The thyristor is disposed in the mechanical press-pack structure. The mechanical press-pack structure includes: a first terminal electrode that is configured to connect the first planar electrode to the first conductor, wherein the first terminal electrode is resiliently supported by a spring assembly; and a second terminal electrode that is configured to connect the second planar electrode to the second conductor. The press-pack structure forms a protective cover enveloping the thyristor.
