Abstract
A switch includes: a hermetic vessel filled with an insulating medium; an insulating spacer dividing the hermetic vessel into a first heretic space and second heretic space; an electrode fixedly penetrating through the insulating spacer; and a first circuit breaker part inserted between a first conductor and the electrode in the first hermetic space and serially connecting a second conductor in the second heretic space in a closed state, and having a first contact including the electrode and a first driver driving the first contact. The first circuit breaker part is a vacuum circuit breaker having the first contact housed in a vacuum vessel and a second circuit breaker part having the second contact larger in dielectric strength than in the vacuum circuit breaker. In an interrupting operation from the closed state, the first contact and the second contact are opened, and the first contact is closed when or after the second contact is opened.
