At present, the common intelligent switch panel in the market has various forms. From the number of keys, there are fewer one-key switches and more six-key switches; from the key form, some use the touch switch button, and some use the touch switch button. There are more or less disadvantages to these types of products: 1. the number of keys on a single panel is limited. It is very difficult to integrate more key functions, and users need more switch panels to achieve the expected effect, which causes cost increase, and the more switch panels are not beneficial to stability and maintainability of the system; 2. the key functions cannot be flexibly adapted. For convenience in use, each key on each switch panel in the existing product needs to be engraved in advance according to function setting to distinguish, such as 'curtain open', 'curtain close', 'reading mode', 'sleep mode', and the customized engraving later cannot be changed, so that the use scene is limited.
