NOVELTY - This new utility model claims of one base layer thin film of overload protective switch, the switch comprises oxidation graphene film, graphene film reduction, the copper and copper oxidation graphene film and graphene thin film through pressure reduction adhesive is double layer composite film, double layer composite film and one end fixed on copper of, for electric conduction glue , the other end and nature contact copper sheet. This new utility model is double layer composite film along with the change of power flow size with bend and stretching of two state, similar to fuse and overload protection of way, a kind of double state, but the fuse is disposable device, then this new utility model can repeat use, and structure is simple, the carbon material content nature, environment-friendly.
