The wiring of non-neutral switch is exactly the same as that of the traditional switch, meaning that the input line into the wall switch is only one live line, while the other input neutral line is directly connected to the load without passing through the switch, 

so there is only one input line on the wall switch which is live line.

The single fire wire switch can be used in any wiring situation.For houses that have been decorated that have only one fire wire and the common switch on the wall surface, can be directly replaced to control the household lights.
