POWER SUPPLY CONTROL DEVICE

Provided is a power supply control device. The power supply control device includes a plurality of semiconductor switches that are connected in parallel between two power sources and control the supply of power to a load that is connected to the two power sources via the plurality of semiconductor switches, the power supply control device including a temperature detection unit that detects a rise of temperature due to heat that is produced from at least one of the plurality of semiconductor switches, and a switching control unit that executes control that switches the plurality of semiconductor switches from OFF to ON if the temperature detection unit detects a temperature that is at least a threshold temperature.
