An electronic apparatus, a distribution panel, and a power source work mode switching circuit thereof

A power source work mode switching circuit is used for controlling a first power supply unit and a second power supply unit to switch between a first work mode and a second work mode. The power source work mode switching circuit comprises a voltage follower module, a comparison module and a switch module. The comparison module is used for comparing the voltage of a first control signal output by the first power supply unit and the voltage of a second control signal output by the second power supply unit with a reference voltage, controls turning-on/turning-off of the switch module according to comparison results and further controls whether the voltage follower module works. When the voltage follower module works, the first and second power supply units are in the first work mode. When the voltage follower module does not work, the first and second power supply units are in the second work mode. The power source work mode switching circuit can switch the work modes of the first and second power supply units a
