摘要： An illuminating membrane switch includes an upper membrane sheet, an electroluminescent device and a lower membrane sheet. The electroluminescent device is interposed between the upper membrane sheet and lower membrane sheet on which switch circuits are printed. In addition to emitting rays through the upper membrane sheet, the electroluminescent device has a plurality of openings allowing the switch circuits of them to contact each other. The keyboard utilizes the illuminating membrane switch to detect any input of keystroke and light up the symbols on the surfaces of key caps for a user to identify the function or alphabetic input of each key cap.

摘要： A safety circuit is provided for a ballast of an electro-luminescent (EL) lamp. The EL lamp had an electrical ground shield on at least a portion thereof and has a separate ground lead. The ballast is an isolated ballast with a line input being isolated from an output. The ballast is constructed and arranged to be electrically connected with the separate ground lead. The circuit includes a current sensing structure constructed and arranged to connect between the separate ground lead and a potential ground of the ballast. In the event a user contacts the EL lamp to replace the EL lamp or contacts a defective EL lamp, the ballast is shut down based on a value of current sensed by the current sensing structure.

摘要： A current limiting device includes a constant current source circuit constructed and arranged to be connected to a direct current input voltage source and to regulate electrical current and a resonance source circuit receiving current from the constant current source circuit. The resonance source circuit is constructed and arranged to be electrically connected with an electro-luminescent (EL) lamp so that the EL lamp receives alternating current. The constant current source circuit and the resonance source circuit are constructed and arranged such that when current flows from the constant current source circuit to the resonance source circuit and to the EL lamp, a maximum peak current received by a user contacting an output of the device or contacting the EL lamp is less than about 0.7 mA.
