Detailed ways

As shown in Fig. 2, in the non-leakage type single live wire switch system of the present invention, the input end and output end of the execution unit are respectively connected to the live wire input L end and the live wire output L1 end. The L end of the FireWire is also connected to an adaptive charging system for charging, and the adaptive charging system is connected to an energy storage unit for controlling the charging and charging of the energy storage unit.
