Claim 3:
4. A switch module with an automatic switching function according to a load, comprising:
a source resistor;
a control circuit, electrically connected to the source resistor, and having a first comparator, a second comparator, a first resistor, and a second resistor, wherein the control circuit is configured to automatically determine, by the first comparator and the second comparator, whether the load is light or heavy according to a voltage divided by the first resistor and the second resistor, and a voltage of the source resistor, and generate, by the first comparator or the second comparator, a voltage control signal;
a drive circuit electrically connected to the control circuit and a switch circuit, wherein the drive circuit is configured to transmit a received gate input signal to the switch circuit according to the voltage control signal; and
the switch circuit comprising a first switch and a second switch, wherein the switch circuit is configured to bring the first switch or the second switch in a conducting state according to the gate input signal,
wherein the first switch is a GaN transistor and the second switch is a MOSFET transistor.
