At present, a lot of intelligent electronic switches controlled in a networking mode such as wireless radio frequency, WIFI, Bluetooth and ZIGBEE appear on the market, but because the working current of electronic circuits such as WIFI, Bluetooth and ZIGBEE is large, the electronic circuits can only be connected into a commercial power zero-live wire in the switch, and the voltage of the switch power supply in the switch is reduced to supply the electronic circuits such as WIFI, Bluetooth and ZIGBEE for use. For the switch of zero fire power supply, because a zero line needs to be added in the corresponding switch bottom box, but the following disadvantages exist: one, many wires are laid down in the whole room, which increases the wiring cost. And secondly, because a zero line is additionally arranged in the switch bottom box, the switch bottom box is provided with the zero line and the live wire, and the two wires can be short-circuited and have risks such as fire and the like if being accidentally touched together. Thirdly, the most fundamental reason is based on electrician traditions, which are difficult to change. Therefore, in order to replace the old-fashioned mechanical switch and avoid rewiring, the intelligent switch is required to be compatible with the old-fashioned switch and can directly replace the old-fashioned switch. There is a need for a power-taking method that can be controlled without changing the existing wiring method, so as to realize the above intelligent control.
