A switching device is for use with electronic apparatuses and for use in transmitting data and power therebetween automatically or manually. The switching device includes a first transmission module, voltage dividing unit, second transmission module, switching module, hub module, expansion unit, and switching units. The switching device switches automatically between a plurality of path configurations formed from the switching module and the hub module according to a voltage change generated because of connection of the first transmission module and the electronic apparatuses, such that the electronic apparatuses can transmit data and power through the path configurations. Alternatively, the switching units change one of the path configurations manually to allow the electronic apparatuses to transmit data and power through one of the path configurations. |
