Claim:
1. An electrical device, being either a power plug or a receptacle, having an over-temperature protection function, comprising: input side phase and neutral lines and output side phase and neutral lines; a reset switch for electrically connecting and disconnecting the input side phase and neutral lines and the output side phase and neutral lines; a solenoid mechanically couplet to the reset switch, wherein when a current flows through the solenoid, the solenoid operates the reset switch to disconnect the input side phase and neutral lines from the output side phase and neutral lines; two or more electrical conductor plates, include at least a phase plate and a neutral plate, electrically coupled respectively to either the input side phase and neutral lines or the output side phase and neutral lines; at least one temperature-controlled switch, disposed in direct or indirect thermal contact with at least one of the electrical conductor plates, the temperature-controlled switch including two metal strips that are either in contact with each other or separated form each other based on their temperature, wherein the temperature-controlled switch is electrically connected in series with the solenoid between the output side phase and neutral lines, and wherein the temperature-controlled switch is in an open state when its temperature is below a predetermined threshold temperature and in a closed state when its temperature is at or above the predetermined threshold temperature, wherein when the temperature of the temperature-controlled switch is at or above the predetermined threshold temperature, the temperature-controlled switch is closed, a current flows through the temperature-controlled switch and the solenoid between the output side phase and neutral lines, and the solenoid operates the reset switch to disconnect the input side phase and neutral lines from the output side phase and neutral lines; and thermally conductive materials disposed between the temperature-controlled switch and the phase plate and between the temperature-controlled switch and the neutral plate.
