A rotating plug includes an insulating main body, multiple conductive prongs, multiple conductive connecting terminals, and an insulating rotating member. Electrical wires are disposed in the insulating main body. The conductive prongs are electrically connected with the electrical wires, respectively. Each conductive connecting terminal includes a fixed portion and a swing portion pivotably connected to the fixed portion. The fixed portion is mounted to the insulating main body and electrically connected to a corresponding electrical wire. The swing portion is mounted to the insulating rotating member. The conductive prongs are mounted to the insulating rotating member and electrically connected with the swing portions, respectively. The fixed portions are electrically connected with the electrical wires, respectively. When the swing portions of the conductive connecting terminals rotate, the swing portions may drive the insulating rotating member and conductive prongs to rotate together therewith. The rotating plug is flexible and convenient in use.
