The present invention discloses an isolation grounding switch device and a solid insulating switch using the same. The isolation grounding switch device comprises an insulating chamber in which an isolation switch, a grounding switch and a transition terminal between a leading-out terminal and a grounding terminal are arranged. The two switches each has a hinge terminal at one end and a contact terminal at the other end, and is in transmission connection with a driving mechanism for switching the corresponding switch in a predetermined stroke. The hinge terminal of the isolation switch is in hinge contact with the leading-out terminal. A leading-in terminal and the transition terminal are distributed in the switching stroke of the isolation switch and are in connection and disconnection cooperation with the contact terminal of the isolation switch. The hinge terminal of the grounding switch is in hinge contact with one of the grounding terminal and the transition terminal, and the other one of the grounding terminal and the transition terminal is disposed in the switching stroke of the grounding switch and in connection and disconnection cooperation with the contact terminal of the grounding switch. Besides, the space occupied by the two switches in rotation is relatively small, facilitating the miniaturization of the isolation grounding switch device.
