At present, there are hundreds of types of home smart lighting switches, and their brands are still increasing. The smart switches used in the market are just a few technologies: power carrier, wireless, and cable.

    
• The power carrier switch uses the power line to transmit the signal. The switch needs to set the encoder, which will be interfered by the power line clutter, which makes the work very uncomfortable and often causes the switch to lose control. The price is very high, and there are more additional devices (such as wave chokes, filters, etc.). There are more installation equipments, and the probability of getting up is higher. The after-sales service is very troublesome and requires professionals to install.
    
• The wireless switch uses RF to transmit signals. The switch is often interfered by radio waves, so that the frequency is not chaotic and easily lost control. The operation is very cumbersome and the price is very high. There are also many additional devices (receiving modules, modems, centralized controllers). After-sales is also very troublesome and requires a professional to install.
    
• Bus switch, also known as the third-generation switch, uses signal lines to transmit signals. It is relatively non-disruptive and anti-interference. The earliest bus is to concentrate all the wires in one position. This position is divided into signal lines to the position of each switch (such as the bedside switch of the hotel), which leads to troublesome wiring installation and requires professional installation.  The advantages of the bus system: no chaos and anti-interference ability, the signal goes to the special signal line to transmit, to achieve communication between the switch and the switch. It can be installed by ordinary electricians by using the wiring of ordinary switches.

The third generation of smart switch products have the following benefits

    
• The product is technically perfect, so the transmission speed, non-disorder, anti-interference ability is very good.
    
• The product has a reasonable circuit safety design in the design concept to avoid losses such as short circuit and burnout of the switch.
    
• Independently developed products have low power loss, fast heat dissipation and long service life.
    
• The product is very strict in quality control and decisively implemented in accordance with ISO 9001 ISO9002. High quality electronic components are used inside the product.

Performance Features
The focus of the intelligent switch is not good chaos, fast transmission speed and strong anti-interference ability. The intelligent switch uses a special signal line alone, and is not subject to radiation clutter such as power lines, radios, etc., and the product handling is not very messy. The non-disorder of function will determine the speed and anti-interference ability of the transmitted signal.
