A power socket device having switches is disclosed and has a housing, socket units, two conductive frames and switch units. The housing has bolt holes. Each of the socket units has a socket body and a pair of conductive terminals. The socket body is formed with a pair of terminal slots. The socket unit can be received in the housing, and slid upward and downward therein. The conductive terminals are inserted in the terminal slots, and selectively in contact with or disconnected from the conductive frames. The socket body has an engagement hole. The switch unit is inserted into the bolt hole, and selectively abutted against the socket body or engaged in the engagement hole, so that the socket unit can be positioned on a predetermined position on a vertical direction. Thus, it is unnecessary to unplug a plug of an external appliance when switching on or off the power.
