IN-VEHICLE SWITCHING DEVICE

A series switch is connected between a negative electrode of a first battery and a positive electrode of a second battery. A first parallel switch is connected between a negative electrode of the second battery and a point that is between the series switch and the negative electrode of the first battery. A second parallel switch is connected between a positive electrode of the first battery and a point that is between the series switch and the positive electrode of the second battery. A first pyro-fuse is connected between the negative electrode of the first battery and a point that is between the series switch and the first parallel switch. A second pyro-fuse is connected between the positive electrode of the second battery and a point that is between the series switch and the second parallel switch.
