1. A power supply circuit comprising:
a first power source conduction path provided between a power source and a first power transmission bus;
a first load conduction path provided between the first power transmission bus and a load;
a second power source conduction path provided between the power source and a second power transmission bus; and
a second load conduction path provided between the second power transmission bus and the load,
wherein the power supply circuit further comprises:
a first positive electrode switch and provided in a positive wire of one of the first power source conduction path or the first load conduction path, the first positive electrode switch being configured to switch between an electrically connected state and an electrically disconnected state of the power source and the first power transmission bus or of the first power transmission bus and the load;
a first negative electrode switch provided in a negative wire of the other of the first power source conduction path or the first load conduction path at which the first positive electrode switch is not provided, the first negative electrode switch being configured to switch between an electrically connected state and an electrically disconnected state of the power source and the first power transmission bus or of the first power transmission bus and the load;
a second positive electrode switch provided in a positive wire of one of the second power source conduction path or the second load conduction path, the second positive electrode switch being configured to switch between an electrically connected state and an electrically disconnected state of the power source and the second power transmission bus or of the second power transmission bus and the load; and
a second negative electrode switch and provided in a negative wire of the other of the second power source conduction path or the second load conduction path at which the second positive electrode switch is not provided, the second negative electrode switch being configured to switch between an electrically connected state and an electrically disconnected state of the power source and the second power transmission bus or of the second power transmission bus and the load.
