1. A power supply switching circuit comprising:
a power supply output terminal electrically connected directly to a cathode of a main power supply side diode and a cathode of a standby power supply side diode;
power supply output circuitry configured to output a main power supply voltage onto the power supply output terminal when control signal output circuitry detects that the main power supply voltage is higher than a reference voltage.
