The use of household electrical appliances are in standby state, the standby power consumption not only, and \eat\ the city is amazing, the average family household standby power consumption has accounted for around 10% of total power, and will release a large amount of carbon dioxide, air bad, accelerated warming. The utility model provides an automatic reminding device, its principle is based on the principle of the current transformer, capacitor discharge, to remind people to actively turn off the power switch according to the load change in the operation of household appliances, to achieve energy-saving shutdown. The utility model can be installed in the circuit of various household devices, can be made into a small or micro, can also be used in fixed socket or multipurpose socket, can also be made to remind the automatic conversion socket with drag line automatic reminding socket or without drag lines. The utility model not only can save a large amount of electric resources, but also has the advantages of environmental protection, convenient use, practicality, safety and good effect.
