Features: Introduction: Adopt high-efficiency low-energy-consumption switching power supply scheme with wide power supply range static and no heat generation and good stability. Advantages: Strong anti-interference ability and multiple functions. Strong load capacity and long durability. Convenient to Use: Instead of the traditional manual switch it can realize the function of remote on/off and control various lamps and home appliances from a long distance. Fireproof Material: The exterior is made of fire-retardant material which is safe to use. Wear resistance high temperature resistance and strong flame retardant. Application Fields: Great versatility widely used in smart home lighting control security monitoring agriculture industry and other fields.
