1. The basic principle of the touch switch
The smart touch switch is a switch device that controls the on and off of the circuit through touch operation. Its basic principle is based on capacitive touch screen technology. It determines the touch action by detecting the tiny current changes generated when the human body touches it, and then realizes the control of the switch.
2. The working principle of the smart touch switch
Capacitive sensing: The surface of the smart touch switch is covered with a transparent conductive film. When the user touches the surface of the switch, a capacitor is formed between the human body and the conductive film. Since the human body has a certain capacitance, when the finger touches the surface of the switch, it will change the original capacitance distribution, thereby forming a new capacitance.
Signal detection and processing: The smart touch switch integrates a highly sensitive signal detection circuit that can detect this tiny capacitance change. This change is converted into an electrical signal through the processing circuit, and amplification, filtering and other operations are performed for subsequent processing.

Control execution: The processed electrical signal will be transmitted to the control chip. The control chip determines the type of touch action (such as single click, long press, etc.) according to the received signal and issues corresponding control instructions. These instructions will drive the switch actuator to act, thereby realizing the control of the circuit on and off.
3. Features of smart touch switches
Convenience: Smart touch switches do not require physical buttons, and can be operated with just a light touch, providing users with a more convenient user experience.
Aesthetics: The smart touch switch has a simple and stylish appearance, which is easy to integrate with various home decoration styles to enhance the overall aesthetics.
Intelligence: The smart touch switch can be connected to other smart home devices to achieve remote control, voice control and other functions to meet the diverse needs of users.
