Abstract
Objects of the invention relate to a detachable breakaway power supply device that can be selectively coupled to an electrical appliance. A first coupling element is carried by the appliance and a second coupling element is carried by the detachable power supply device. The power supply device is carried by a conventional power supply cord. Attractive magnetic forces between the first and second coupling elements permit selective, removable attachment and electrical contact between the appliance and the power supply device. This arrangement provides a breakaway mechanism in which disturbance of the power supply cord, e.g., by tripping, results in the separation of the power supply device from the appliance to prevent overturning of the appliance and spilling of its contents.
