Does the switch still consume power after entering the zero line?

In fact, switching to the zero line belongs to micro power consumption, of course, the power consumption is very small, which is equivalent to micro leakage. Why? Because it will cause induced leakage when the weather is wet, LEDs or fluorescent lamps are easy to turn off the lights and then dim. Power consumption should not be underestimated. In fact, there is a loop for electricity consumption. Go to the electricity meter, even if it is induced!
