A charging socket comprises a casing. A press and detain switch and a circuit board are accommodated and positioned inside the casing. A movable base is positioned above an opening of the casing. The movable base is connected with an end of a press portion. One end of the movable base is pivotally connected with the casing. At least one plugging base is inbuilt inside another end of the movable base. The plugging base is electrically connected with the circuit board. Accordingly, when the movable base is pressed to move together with the press portion and expose the plugging base, an electrical device can be charged electrically. When the movable base is pressed to hide the plugging base, the plugging base is open-circuited for safety.
