#smarthomealivehome | What is a zero fire switch？

The zero fire switch means that there is a live wire and a neutral wire connected to the switch in addition to the line connecting the switch to the light. The zero fire switch must be installed after the home circuit is remodeled during the decoration. After the renovation of the water and electricity, there is no way to add a zero fire switch. Wire.

Single fire switch: Except for the line connecting the switch to the light, there is only one fire wire connected to the switch (traditional switch).

The problem with the single-fire switch is that when the circuit is disconnected, the switch itself is powered off, so if we can achieve a switch that does not physically disconnect the wire and can control the light, this problem can be solved. Engineers have modified the switch: the switch is not a mechanical switch to physically disconnect the circuit, but a load is added to the circuit of the switch and the light bulb. When the switch is turned off, due to the presence of the load, only a small current flows through the switch and the light bulb. The current passed is small enough to light the bulb while maintaining the switch, thus solving the problem of the single fire switch.

Now more and more people want to install smart homes in their homes when they are decorating their new houses, and enjoy the smart life brought by technology. When we search for smart switches on the Internet, we will find that the switches are divided into two types: single fire switch and zero fire switch, so we need to pay attention and distinguish them.
