Wall Switch

Introduction

       With the progress of science and technology, more and more intelligent products have been used for monitoring the resources in daily life and pushing the cloud strategies and other value-added service scenarios. Along with the popularity of intelligent mobile terminal, intelligent wall switch has gradually become the priority of wall switches, which has expanded the use scenarios linked with smart home on the basis of remote control switches. In human-computer interaction, traditional mechanical buttons have been evolved to touch keys, wheel/slider control, and even proximity sensing scenarios.
