The utility model provides a dual power supply automatic change-over switch operating mechanism and a dual power supply change-over switch, the operating mechanism comprises a transmission mechanism which is driven by a power mechanism to be movably installed on a switch body, and the transmission mechanism and a moving contact assembly are arranged in a linkage mode. The first position and the second position respectively correspond to a common position and a standby position of the moving contact assembly; and the damping mechanism is arranged on the switch body and is in damping fit with the switch body when the transmission mechanism is switched between the first position and the second position. Therefore, the switching speed of the transmission mechanism is slowed down, it is guaranteed that after the arc of the static contact on one side is extinguished, the moving contact is in contact communication with the static contact on the other side, and safety and reliability are improved. 本实用新型提供一种双电源自动转换开关操
