Background
The switches of common families at home and abroad are mostly wired by a single live wire, so that a single live wire switch needs to be arranged in a circuit, and the single live wire switch needs to supply power when working, which means that under the condition of no zero line, the power supply part of the single live wire switch can supply power for a control circuit of the single live wire switch when the single live wire switch is turned on (on state) and turned off (off state).
1. In an off state, weak current flowing through a load is mainly utilized to be converted by a switching power supply to get electricity, different lamps allow different currents to flow, if the currents are larger than the allowed currents, the lamps enter an operating state, and the load immediately exits the operating state because the switch is in the off state and cannot provide voltage and current for the load to operate, so that the load is frequently switched between operation and non-operation, and the situation can cause the load allowing small current to flow, such as an energy-saving lamp, an LED lamp, a fluorescent lamp and the like in a household lamp, to frequently flicker when the switch is not turned on. Meanwhile, if the fluorescent lamp adopts the inductive ballast, the allowed current is very small, the obtained current is almost zero, and the single-fire switch cannot work normally due to insufficient power supply.
