1. A method for automatically switching a switch module according to a load, comprising:
automatically determining, by a first comparator and a second comparator, whether the load is light or heavy according to a voltage divided by a first resistor and a second resistor, and a voltage of a source resistor, and generating, by the first comparator or the second comparator, a voltage control signal; and
transmitting, by a plurality of transistors, a received gate input signal to a first switch or a second switch according to the voltage control signal to selectively bring the first switch or the second switch in a conducting state,
wherein the first switch is a GaN transistor and the second switch is a MOSFET transistor.
