Abstract: A method for manufacturing low cost electroluminescent (EL) illuminated membrane switches is disclosed. The method includes the steps of die cutting, embossing or chemically etching the metal foil surface of a metal foil bonded, light transmitting flexible electrical insulation to simultaneously form one or more front capacitive electrodes, membrane switch contacts and electrical shunt, electrical distribution means and electrical terminations that together form a flexible printed circuit panel. This continuous flexible printed circuit substrate is then used with a precisely positioned indexing system.

Abstract: A method for manufacturing low cost electroluminescent (EL) illuminated membrane switches is disclosed. The method includes the first step of die cutting, embossing or chemically etching the metal foil surface of a metal foil bonded, light transmitting flexible electrical insulation to simultaneously form one or more front capacitive electrodes, membrane switch contacts and electrical shunt, electrical distribution means and electrical terminations that together comprise a flexible printed circuit panel. This continuous flexible printed circuit substrate is then coupled to a precisely positioned indexing system. Next, the front metal foil capacitive electrodes are coated with a light transmissive electrically conductive layer.

Abstract: A method for manufacturing low cost electroluminescent (EL) lamps is disclosed. The method of the present invention includes the first step of die cutting, embossing or chemically etching the metal foil surface of a metal foil bonded flexible electrical insulation to simultaneously form one or more rear capacitive electrodes, electrical terminations, optical registration fiducial indicia, and a continuous carrier means that is then coupled to a precisely positioned indexing system. Next, the rear metal foil capacitive electrodes are coated with a capacitive dielectric layer precisely isolating the rear electrode form. In the third step, a layer of electroluminescent phosphor ink is applied to the rear capacitive electrodes to precisely form areas of illumination. In step four, a layer of light transmissive and electrically conductive ink is applied to cover the EL phosphor layer.

Abstract: A method for manufacturing low-cost electroluminescent (EL) lamps is disclosed. The method of the present invention includes the first step of die cutting, embossing or chemically etching a metal foil to form one or more rear capacitive electrodes. Next, the capacitive electrodes are bonded to a paper core stock which is coupled to a precisely positioned indexing system. In the third step, a layer of EL phosphor ink is applied to the capacitive electrodes to precisely form the areas of illumination. In step four, a layer of conductive ITO ink is applied to cover the layer of EL phosphor ink. Next, in step five a transparent polyester film or ultraviolet activated dielectric coating is applied to the entire surface of the lamp. Finally, in step six electrical terminations are provided to the rear capacitive electrode and the layer of conductive ITO ink.

Abstract: An adapter having solderless wire terminals for receiving the wire leads from an electrical equipment such as a radio or stereo player set is installed on the back of such set. Such terminals have solderless spring connectors for the wire leads, these connectors employing a pair of opposing apertured fingers which overlap when manually urged together against the spring action to permit the insertion of a wire lead in the aperture thereof and to be retained therein by the spring action. The equipment or stereo set is removably installed in a mounting frame which is mounted in the vehicle. The mounting frame has a terminal therein which the terminal of the set matingly engages to provide electrical connections therebetween. The terminal of the mounting frame has solderless spring connectors similar to those of the terminal of the equipment, such connectors receiving the various wiring leads from the equipment to the power source, speakers, etc.
