Claim:
1. A switch comprising: a sealed housing filled with an insulative medium; a plurality of contactors each comprising a contact; a plurality of operation units disposed outside the sealed housing and actuating the contact; an insulative spacer dividing an interior of the sealed housing into a plurality of internal spaces, a number of the internal spaces being consistent with a number of the contacts; and an electrode passing completely through the insulative spacer, and being fastened to the insulative spacer, wherein; the contactor is provided one by one for each internal space; at least one of the contactors includes a linkage which passes completely through the sealed housing while maintaining an air tightness of the interior of the sealed housing, is connected with the operation unit, and transmits actuation force by the operation unit to the contact, wherein among the contactors: at least one of the contactors comprises a vacuum contactor that comprises a vacuum valve with the contact; and at least one of the contactors comprises a contactor with the contact that has a larger dielectric strength than a dielectric strength of the contact of the vacuum valve, all of the contacts are electrically connected in series via the electrode; each of the operation units actuates the corresponding contact, the operation unit of at least one of the contactors comprises: when the coil is excited, repulsive force is generated between the coil and the opposing conductor, and thrust force is applied to the movable shaft.
