The invention relates to an automatic transfer switch with double power sources. The automatic transfer switch comprises a substrate, a base, a switching control device and breaker modules arranged on the two sides of the switching control device. The switching control device comprises two drive sliders and a switching mechanism. The switching mechanism comprises a motor and a switching piece fixedly arranged on a motor rotation shaft. The drive sliders and the substrate are in sliding fit. One ends, matched with the switching piece in a linkage mode, of the drive sliders are provided with an upper stop block and a lower stop block which are arranged on two layers. The switching piece comprises a lower first ejection block and an upper second ejection block which are arranged on an upper layer and a lower layer respectively. Through the first ejection block, the second ejection block, the upper stop block and the lower stop block, turning on and off of the breaker modules on the two sides are controlled respectively without interference when the switching piece rotates. When the first ejection block on one side makes contact with the lower stop block, the second ejection block on the other side makes contact with the upper stop block, and the effect that one breaker module is turned on and the other breaker module is turned off is achieved.
