This is an intelligent switch without a frame. Minimalist design, with metal panels, exudes a strong sense of quality. Unlike most other switches, the innovative design of the key structure allows the user to click on any position of the board, and keep the handle uniform and consistent. Although the panel is made of metal, it has a good wireless communication function and can be built into a smart home system. In addition to local control, it can also control lighting, curtains, air conditioning, and other functions remotely via mobile phones.
