A DC circuit switching apparatus is connected between an automobile battery and a motor-side circuit and cuts off current that flows in two directions. The DC circuit switching apparatus includes a breaker that cuts off current, a first voltage holding circuit, which is constituted by a first diode and a first capacitor that are connected in series, that is provided in parallel to the breaker and is configured to allow power supply from the automobile battery to the motor-side circuit, and a second voltage holding circuit, which is constituted by a second diode and a second capacitor that are connected in series, that is provided in parallel to the breaker and is configured to allow power supply from the motor-side circuit to the automobile battery.
