In the hydraulic operating device for a switch, the piston is connected to the hydraulic operating part and the pump unit, and the piston is provided with a gas sealing inlet to the gas chamber of the accumulator, and the piston is filled with air from the hydraulic oil side connection port. The manifold attached to the accumulator is provided with an opening that faces the gas filling inlet via the hydraulic oil side connection port of the accumulator and penetrates from the accumulator side end face to the opposite end face of the accumulator, and this opening 1. A hydraulic operating device for a switch, characterized in that it is closed so as to be openable and closable by a closing member having a seal portion. (2) The hydraulic operating device for a switch according to claim 1, which uses a check valve and a plug as a gas sealing inlet of a piston. (3) A piston with a piston protrusion on the oil chamber side is used as the piston in the accumulator, and the tip of the piston protrusion can be inserted into the opening of the manifold, so that the manifold and the opening are connected at the time of insertion. A hydraulic operating device for a switch according to claim 1, which is provided with an oil-tight seal portion on a joint surface.
