    • PROBLEM TO BE SOLVED: To provide a control device driving at least two components of a switch gear in a conditioned manner, in which one component performs shielding in vacuum. SOLUTION: The device has a vacuum first component of a switch gear (1) having a pair of contacts (5, 6) which can be separated for shielding purpose. The control device has a main drive shaft (2) for driving a second component of a switch gear (10), immersed in a vapor insulating fluid (G 2 ) of gas phase included with prescribed pressure (P 2 ), and further has an auxiliary shaft (4) for enabling a moving contact (5) of a first component of the switch gear (1) to be driven. The auxiliary shaft (4) passes through a wall (7A, 7'), separating a cubic volume of the insulating fluid (G 2 ) of gas phase from the other cubic volume (V 1 ) of a fluid (G 1 ) having a lower pressure (P 1 ) in a manner of preventing leakage, and obtains a certain pressure (F p ) related to a contact pressure generated by the impression of pressure difference between respective pressure (P 2 , P 1 ) of two fluids (G 2 , G 1 ) on the auxiliary shaft (4).
