In a grounding switch for an encased high-voltage switching system, the movable switching piece is moved by a rotating drive shaft, which passes through the housing of the grounding switch. In order to design the contact elements, which transfer the ground potential to the movable switching piece, in as simple a manner as possible, the drive shaft consists of electrically conductive material and is introduced into the housing in an insulated manner. The drive shaft is connected with means to transfer the ground potential, e.g. a current strip, outside the housing. The drive shaft therefore serves both to transfer force and to transfer potential. A switch blade is designed to be elastically deformable in part and serves as the movable switching piece. Such a grounding switch for an encased, compressed-gas-insulated high-voltage switching system can thus be used also as an insulated grounding switch, to carry out measurements.
