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. 

Key Features

  • High-power capacity: The 20A rating allows it to manage high-power devices like air conditioners, boilers, and water heaters safely.

  • Remote and voice control: You can turn appliances on or off from anywhere using a mobile app or through voice commands with assistants like Alexa and Google Assistant.

  • Energy monitoring: Many models include a feature to track and monitor your real-time energy consumption, helping you manage electricity bills.

  • Scheduling and timers: Set schedules to automatically turn appliances on or off at specific times, providing convenience and energy savings.

  • Touch-sensitive glass panel: Features a modern, easy-to-clean tempered glass surface with touch controls.

  • WiFi connectivity: Connects directly to your home's 2.4GHz Wi-Fi network, usually without needing an extra hub.

  • Installation requirement: A neutral wire is typically required for proper installation and operation.

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.
