1. The intelligent household appliance switch is a running unit with the same shape and installation size as the existing mechanical wall switch, which is put into electronic components or microcomputer control board to realize circuit on-off or circuit change for different appliances according to their own functional requirements. The intelligent household appliance switch uses microcomputer intelligent switch control technology, It can maximize the performance of electrical appliances.
 2. The ON/OFF control is also called BANG-BANG control. Because this control mode is simple and easy to implement, it is used in the control of many household appliances and lighting fixtures. However, conventional switch control is difficult to meet the requirements of further improving control accuracy and energy saving. During the control cycle of conventional switch control mode, its control quantity has only two states, either on, a fixed constant value, or off, and the control quantity is zero. This fixed control mode lacks the characteristics of manual switch control. During the process of manual switch control, People should choose different switch control strategies according to the error and error change trend. For example, in a control cycle T, the time of control quantity output is adjustable as required. Based on human knowledge and experience, according to the actual error variation law and the inertia, pure delay, disturbance and other characteristics of the controlled object (or process), this switching control which selects different control strategies according to a certain mode is called intelligent switching control.
