Title: Current inductive timer socket

Abstract: A current inductive timer socket comprises: a principle relay circuit, a reed relay circuit, a plurality of diodes, a reed relay and a resistance, a counter circuit, a holding circuit, a time switch circuit and amplification circuit. When the electric appliance is in use, a signal of voltage drop produced at both ends of the rated resistance will be amplified by the operational amplifier and then transmitted to the counter circuit and an overload detecting circuit, making the counter circuit start to count automatically, and thus time operation is carried out. Further, when electric appliance is overloaded or in the case of short circuit, the power source can also be cut off automatically.
