Abstract High-voltage power switch High-voltage power switch with an arc contact (1) and a spatially separated rated current contact (6), with the movable part of the rated current contact (6) taking the form of an external hollow cylinder for delimiting a storage space (11) for a pressurized quenching gas. The hollow cylinder (10) is made of a one-piece precision casting of contact material, especially a CuCr alloy, the jacket of which is stiffened by three inwardly projecting flange-like projections (12, 13, 14). This design provides a light structure for a bridging circuit component for a rated current contact requiring comparatively little driving power for its operation.
