Smart WiFi Touch Switch 20A
A Smart WiFi Touch Switch 20A is a high-power electrical switch that can be controlled remotely via a smartphone app or voice commands like Alexa or Google Home. The "20A" rating means it can handle up to 20 amps of current. It is suitable for controlling heavy-load appliances such as air conditioners, boilers, and water heaters. These switches feature a touch-sensitive, tempered glass panel. Touch Switch offers features like energy monitoring, and requires a neutral wire for installation.

Working Process
A smart Wi-Fi touch switch 20A is specifically designed to control high-power, high-current electrical loads up to a maximum of 20 amperes (approximately 4400 watts at 220V-240V). It functions like a standard smart switch but is built with heavy-duty internal components to safely manage the electrical current required by powerful devices.
Step-by-step working process
Input: A command is initiated via a touch panel, smartphone app (e.g., Tuya Smart, Smart Life, etc.), or voice assistant such as Amazon Alexa or Google Assistant.
Signal transmission and processing: The Wi-Fi module receives the command and sends it to the MCU. The MCU interprets the command and checks it against safety parameters (e.g., if overload protection is enabled).
High-current circuit control: The MCU sends a signal to the heavy-duty relay. The relay physically closes or opens a high-voltage, high-current (up to 20A) electrical circuit in the connected device.
Status Feedback: The operational status of the switch is tracked by the MCU and communicated to the smartphone app in real time.
