The invention has an object to provide an operating device or vacuum switch which permits reduction in the overall height of the operating device and improves installation convenience. In order to solve the above problem, an operating device according to the present invention is characterized by including an electromagnetlocated in a caseand fixed to the casethrough a fixing part, a capacitorlocated at an end in the case, a control boardlocated opposite to the capacitoracross the electromagnet, an auxiliary contactlocated above the capacitor, a movable part to move by a magnetic force generated from the electromagnet, and a power transmission section to operate in conjunction with movement of the movable part. The capacitorand the auxiliary contactare located at heights not exceeding the height of the fixing part for fixing the electromagnet

Operating device or vacuum switch

A vacuum insulating switch gear formed by integrally molding with epoxy resin of a vacuum double-break three-position type switch including a movable contact, a fixed contact, and a vacuum container composed of an insulating cylinder for covering the movable contact and the fixed contact, a lower lid for closing a lower part of the insulating cylinder, and an upper lid for closing an upper part of the insulating cylinder and an operation rod side of the movable contact, and an earthing switch with a vacuum closed container, comprising
