  • Switch with at least one flexible conductive member
    Patent number: 6469267
    Abstract: A switch comprises two substrates coated with conductive elements opposed to each other across a gap. At least one of the conductive elements comprises an intrinsically conductive polymer. The switch completes an electrical circuit when one of substrates is pressed toward the other of the substrates and the two conductive elements touch. The polarity applied to the intrinsically conductive polymer coating is, preferably, negative. The voltage applied to the electrical circuit, is, preferably, less than five volts; more preferably, the voltage applied to the electrical circuit is less than three volts; even more preferably, the voltage applied to the electrical circuit is less than one volt.
