Switching device

A switching device for use in transmitting at least one of data and power between electronic apparatuses when connected thereto, the switching device comprising:

• a first transmission module having a first power connection terminal and a first data connection terminal and connecting to one of the electronic apparatuses via the first power connection terminal and the first data connection terminal to thereby transmit the data and the power;
• a voltage dividing unit connecting to the first power connection terminal and retrieving the power from the first power connection terminal to thereby generate a trigger signal;
• a second transmission module having a second power connection terminal, a second data connection terminal, and a control terminal and connecting to another one of the electronic apparatuses via the second power connection terminal and the second data connection terminal, wherein the second power connection terminal connects to the first power connection terminal, wherein the control terminal switches between a master control configuration and a slave control configuration of the electronic apparatuses connected to the second transmission module;
• a switching module connected to the first data connection terminal and the second data connection terminal;
• a hub module having a plurality of connecting units and a routing unit and connecting to the switching module via the connecting units, wherein the hub module and the switching module together form a plurality of path configurations whereby the data and the power are transmitted between the electronic apparatuses;
• and
• an expansion unit connected to the hub module, wherein the data and the power are transmitted between the expansion unit and the electronic apparatuses in accordance with the path configurations.
