Abstract: A miniaturized electrical system comprises a number of electrical devices interconnected by conductive tape. The electrical devices and metal foil conductors are electrically connected in the system directly or indirectly to the metal foil conductors of the conductive tape and the entire system may be adhesively secured to the surfaces of a miniature device such as a doll house with the metal foil conductors fully covered and protected and adapted to be painted over so as not to be discernible. Brads are used to penetrate the conductive foils either to enhance the electrical connection between directly contacted foils or to establish electrical connection between foils separated by an adhesive strip. The kit of electrical devices and conductive tape features a miniaturized wall outlet which is physically secured to and electrically connected with the conductive tape by brads.
