Single-live-wire intelligent switch

The utility model discloses a single-live-wire intelligent switch. The live wire inlet end and the live wire outlet end are connected in series in a live wire for supplying power to electric equipment; the switching power supply circuit and the rechargeable battery circuit are used as power supplies, when the electronic switch is switched on, the electric equipment is started to work, and the rechargeable battery circuit supplies power, so that the problems that the output current is too low, the requirements of the circuit are difficult to meet and the circuit is not controlled during repeated switching in a single-live-wire power taking scheme in the prior art can be avoided; moreover, the power supply quality of the rechargeable battery is high, so that the single-live-wire intelligentswitch has stronger anti-electromagnetic interference capability when electric equipment works; when the electronic switch is switched off, the switching power supply circuit charges the rechargeablebattery circuit and suppli
