Operating mechanism of automatic change-over switch

The invention relates to an operating mechanism of an automatic change-over switch, which comprises a base, a common electromagnet, a standby electromagnet, an input assembly, an energy storage assembly and an output assembly, and is characterized in that the input assembly comprises two input plates and an input turntable, and the two input plates are coaxially arranged on the outer side of the input turntable; an input driving part in linkage connection with the two input plates is formed on the input turntable, the input plates drive the input turntable to rotate by pushing the input driving part, two input shafts are arranged on the two input plates, push plates are arranged on the common electromagnet and the standby electromagnet, and the push plates are connected to movable iron cores of the common electromagnet and the standby electromagnet. The top end of the push plate is correspondingly arranged above the input shaft on the outer side, an inclined reset face is formed on the upper side of the top e
