System Overview :

The Wall Switch is a power control device designed to remotely manage 100–240 VAC power. The output terminal N is directly connected to the power input terminal N, while the connection between the output terminal L and the power input terminal L is controlled by a built-in relay that opens and closes to regulate power flow. In addition to controlling power, the switch also measures power consumption and includes protection features against overvoltage, overload, and overheating.
