The present invention provides an electronic switching device for a universal serial bus (USB) interface, which can connect several different electronic devices each having a universal serial bus (USB) interface when needed. By manually enabling a switch of the electronic switching device for a universal serial bus (USB) interface, a trigger signal generated from a trigger signal generator will be outputted to a control signal generator to generate a control signal for connecting related electronic devices. A delay signal generator can be added to avoid the intermediate devices being operated unintentionally.
