Date Dec. 7, 1995A power switch module designed to be mounted in gas-filled containers of gas-insulated switchgear is provided, wherein each vacuum switch tube of the power switch has a corresponding rectilinearly movable actuating rod leading into the gas-filled container through a bellows-type seal. The power switch module includes two insulating support devices arranged symmetrically on a partition, between which the corresponding vacuum switch tubes supported by a pole support device and a pole head device. Such power switch modules are used in gas-insulated switchgears.
