Abstract

A power supply switching system includes a switch controlling apparatus, at least two switch apparatuses, alternating current (AC) powers, and a power shelf. The power shelf includes at least two AC inputting ends. Each of the at least two switch apparatuses is electrically connected between one of the AC inputting ends and the AC powers. A number of the AC powers is less than a number of the at least two AC inputting ends. The switch controlling apparatus is electrically connected with each of the at least two switch apparatuses, and controls the at least two switch apparatuses to turn on or turn off. The power supply switching system saves a number of the AC powers while executing an ATS test, thus an efficiency of the power shelf is improved. A switch apparatus is also provided.
