Whether a single-fire smart switch or a zero-fire smart switch needs to be selected according to the actual decoration and wiring conditions: a neutral wire is reserved when wiring the switch box, and the zero-fire smart switch is preferred; there is no neutral wire reserved in the switch box. , when using a single fire switch, it is recommended to use the fifth generation mature and stable XD3390A/XD-KC024A single fire smart switch with single fire wire technology solution.
Some people say that single-firewire smart switches are not stable, and some lights will appear "wisps" or flicker, and may even be damaged after being used for a period of time. This is because there are many single-firewire smart switches, especially some low-end smart switches. For cost reasons, the switch still uses the first-generation RCC single live wire technology whose patent has expired more than ten years ago (its advantages are: low cost, its disadvantages are: poor circuit stability, low load compatibility, and late damage rate higher).
If you choose a single fire wire smart switch, it is strongly recommended to choose a mid-to-high-end single fire wire smart switch from a big brand. These brands generally use the fifth-generation mature and stable XD3390A/XD-KC024A single fire wire technology solution. The switch has the following characteristics:
1) Say goodbye to single fire flickering: It adopts original single fire wire technology, no batteries are needed inside and outside, rejects "pseudo" single fire wire, and does not require anti-flash accessories.
2) Suitable for all types of lamps: such as LED bulbs, energy-saving lamps, fluorescent lamps, fluorescent lamps, filament lamps, LED light strips, tungsten lamps, etc.
3) Concurrently operate traditional dual control: intelligent switches and traditional mechanical dual control switches are linked to achieve overall dual control.
4) No wiring changes are required for installation: direct installation to replace traditional switches without rewiring.
5) Safe and stable performance: It adopts unique relay (non-magnetic latching) anti-stick technology, load range: 3W-3000W, and can pass EM certification test.
6) Remote control is convenient: multiple communication protocols (Zigbee, Bluetooth, RF433, LoRa, NB-IoT) are available.
