Technical scheme of single fire switch

The difficulties of single fire wire power extraction technology mainly include the following aspects:

Maintain the minimum current of the wireless module

When the lamp is turned off, the single fire smart switch is connected to the power grid after being connected in series with the lamp, so the current flowing through the smart switch and the lamp is the same, and the small current will cause the smart switch circuit not to work. If the current is too large, it will lead to problems such as intermittent flash or red wire when the incandescent lamp is turned off.

Second, there is instability in adapting to different load currents.

The change of load type will also cause the change of current, which will lead to the unstable operation of switch control circuit.

Third, the influence of unstable single-fire power supply on the distance of wireless module.

The radio remote control distance is unstable caused by the interference of single fire power supply.
