| 摘要 | A power feeding path switching device includes a relay (RL1). The relay becomes excited when a power supply current flows across the relay in a first direction of a power feeding path, and becomes unexcited when a power supply current flows across the relay in a second direction opposite to the first direction, or when a power supply current does not flow across the relay. The relay in an unexcited state connects the power feeding path with ground, and the relay in an excited state does not connect the power feeding path with ground. | ||||||
