つた時に負荷をOFFする構成である。This is a safety device for the electrical circuit of the human body local cleaning device. The microcomputer stores the switch inputs and the load conditions and load currents for the inputs, and constantly monitors and stores the current actually flowing to the load. In this configuration, the load is turned off when the current pattern becomes different from that of FIG.
