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 electromagnet 14 located in a case 10 and fixed to the case 10 through a fixing part, a capacitor 16 located at an end in the case 10, a control board 18 located opposite to the capacitor 16 across the electromagnet 14, an auxiliary contact 34 located above the capacitor 16, a movable part to move by a magnetic force generated from the electromagnet 14, and a power transmission section to operate in conjunction with movement of the movable part. The capacitor 16 and the auxiliary contact 34 are located at heights not exceeding the height of the fixing part for fixing the electromagnet 14.
