An electric shock proof socket circuit includes a power supply module for stepping down and rectifying an input voltage and then providing the step-down and rectified voltage to a detecting module and a switching module. The detecting module includes a light-emitting unit and a light-receiving unit. The light-emitting unit is used for emitting light for the light-receiving unit. Whether the light from the light-emitting unit is received by the light-receiving unit or not makes the detecting module send corresponding control signals. The switching module controls power output of the socket circuit according to the control signals for preventing an electric shock danger. So the electric shock proof socket circuit has the advantages of security and convenience. |
