The utility model relates to an instant parallel connection converting structure of an automatic change-over switch. The converting structure is mainly composed of a support assembly, a power supply A direction electromagnet assembly, a supporting member, an intermediate connecting rod assembly, a housing, a circuit board assembly, a power supply B direction electromagnet assembly, a bearing balance plate assembly, a fixed seat, and a static contact assembly. The converting mechanism comprises only two states including a state of power supply A opening and power supply B closing and a state of power supply B opening and power supply A closing. Two electromagnets are arranged symmetrically. A single electromagnet assembly controls one state and locks the position state of the structure with a spring and the bearing balance plate assembly. The movable contacts of a power supply A and a power supply B which are installed in the housing are connected together through a power supply A square shaft assembly and a p
