Membrane switch with series resistor

摘要: A membrane switch is formed of an upper layer electrically insulating material, a lower and intermediate material interposed between the material. first conductive printed upon surface second resistive component end portion layer. The provided with opening so as to enable conducting initially engage when moved downwardly by means actuating member produce electrical connection terminals layers which exhibits low current flow corresponding slidable position member, while slidably further in same direction, direct layers, without being therebetween series manner, established exhibit higher within circuit.
