Zusammenfassung:	PROBLEM TO BE SOLVED: To provide an indoor distribution system which hardly causes waveform distortion in a power supply and hardly causes electromagnetic interference. SOLUTION: This distribution system comprises a plurality of parallel control switching circuits A each of which is formed by connecting a zero cross switch 2 in parallel on a power supply side. The plurality of parallel control zero cross switching circuits A and capacitors C2 are connected in series to an AC power supply 4. In each of the parallel control zero cross switching circuits A, a control circuit 1 is provided which closes the zero cross switch 2 when a voltage applied to a load is higher than a first prescribed value and opens the zero cross switch 2 when the voltage applied to the load is lower than a second prescribed value.
