Intelligent switch refers to a unit that uses a combination and programming of a control board and electronic components to achieve circuit intelligent switch control. Switch control, also known as BANG-BANG control, is widely used in the control of many household appliances and lighting fixtures due to its simplicity and ease of implementation. However, conventional switch control is difficult to meet the requirements of further improving control accuracy and energy saving.

The conventional switch control method has only two control states during the control cycle, either on, which is a fixed constant value, or off, with a control quantity of zero. This fixed and unchanged control mode lacks the characteristics of manual switch control. In the process of manual switch control, people need to choose different switch control strategies based on errors and error trends. For example, within a control cycle T, the output time of the control quantity can be adjusted as needed. This type of switch control, based on human knowledge and experience, selects different control strategies according to certain modes based on the actual error variation law and the inertia, pure lag, and disturbance characteristics of the controlled object (or process), is called intelligent switch control.

Compared with mechanical wall switches, it has multiple functional features, is safe to use, and has a beautiful style. Breaking the traditional single function of opening and closing wall switches, in addition to innovative functionality, it also endows switches with decorative embellishments. Smart switches are widely used in various fields such as home intelligent transformation, office intelligent transformation, industrial intelligent transformation, agriculture, forestry, fishery, and animal husbandry intelligent transformation, greatly saving energy, improving generation efficiency, and reducing operating costs, truly achieving intelligent operation in the world.

With the popularity of smart mobile terminals, the connotation of smart switches is also developing, gradually becoming the preferred application for mobile phone control. On the basis of retaining remote control switches, it has also expanded into various composite scenario value-added service models such as energy consumption monitoring in smart homes, node strategy recommendation push in cloud service backends, etc. Smart switches are also undergoing a comprehensive energy deployment stage from a single individual or individual to a family intensive linkage. ​
