Abstract
A power supply switch apparatus includes a first interface, a switch circuit, and a power supply circuit. The first interface includes a first control signal output terminal, a second control signal output terminal, and a third control signal output terminal. Each of the first control signal output terminal, the second control signal output terminal, and the third control signal output terminal outputs a control signal according to an electronic device inserted in the first interface. The switch circuit receives the control signals and outputs a power supply signal accordingly. The power supply circuit receives the power supply signal, and provides a first direct current (DC) voltage or a second DC voltage to the electronic device according to the power supply signal.
