description An operating mechanism of a switch belongs to the technical field of switching devices. Comprising a handle assembly, a toggle connecting rod, a main spring and a rotating shaft, the toggle connecting rod is composed of an upper connecting rod and a lower connecting rod which are hinged to each other, the main spring is hung between the handle assembly and the toggle connecting rod, and the lower connecting rod is hinged to the rotating shaft to drive the handle assembly to act between opening and closing, so that the rotating shaft drives a contact to be separated or closed. And when the contact is in the closed position, the included angle between the upper connecting rod and the lower connecting rod is 178.5-181.5 degrees. The utility model has the advantages that in the opening process of the switch, after the four-bar linkage of the operating mechanism begins to move, the acting moment of the main spring on the four-bar linkage of the operating mechanism is always in the opening direction, the decelerati
