ABSTRACT:
An electric device is provided as an interface between a permanent power source (e.g., an electric wall outlet) and an electrical appliance for interrupting electrical power to the appliance in the event the temperature of either the power cord plug of the electrical appliance or permanent power source rises above a predetermined temperature. The electric device detachably couples to the electric power terminals of both the permanent power source and electrical appliance and is sensitive to the temperature of the aforementioned terminals. The electric device includes first and second temperature switching elements which are responsive to interrupt electrical power from the permanent power source to the appliance when either of the terminals is of a temperature which equates with a first predetermined temperature determined by the first temperature switching element or a second predetermined temperature determined by the second temperature switching element.
