Zusammenfassung:	PROBLEM TO BE SOLVED: To provide an inexpensive gas-insulated switch device wherein its good earthquake resistance is secured suppressing its vibration. SOLUTION: In this gas-insulated switch device, on a floor slab 1, a foundational base 2 is provided to provide thereon a common base 15 via a vibration- isolating device 3. The size of the common base 15 is about half as large as the foundational base 2 and is disposed here a gas-blast circuit-breaker 12 generating a vibration, when operating it. Therefore, through the operation of the vibration isolating device 3, a vertical impact F can be reduced. On the foundational base 2, apparatuses other than the gas-blast circuit-breaker 12 of a cable head, etc., are disposed. Thereby, a horizontal displacement can be confined, and the horizontal natural-frequency of the whole gas-insulated switch device can be made high, to make securable its superior earthquake-resistant performance.
