したことを特徴とする負荷切換回路。 In a switching circuit in which a pair of emitting elements are alternately switched to perform a lighting operation, means is connected to one of the emitting elements to drive the emitting element, and means is connected to the other one of the emitting elements to drive the emitting element. A switch for switching the lighting operation and a power supply circuit for supplying DC voltage to the driving means are provided, so that when the switch is off (or on), one of the emitting elements is lit and the other emitting element is not lit. A load switching circuit characterized in that the circuit is set to
