  • Variable resistor in which an electrode connected to a resistor can not be required
    Patent number: 6239688
    Abstract: There is provided a variable resistor comprised of a resistor formed at a movable member arranged to be reciprocatable, and a slider element attached to a fixing member fixed in opposition to the movable member, slidingly contacted with the resistor. The resistor has the first resistor, the second resistor and the third resistor extending in a reciprocating direction of the movable member and electrically independent from each other, a first resistor pattern having one end of each of the first resistor and the second resistor connected to each other, a second resistor pattern having the other ends of the second resistor and the third resistor. The slider element is comprised of the first slider element, the second slider element and the third slider element slidingly contacted with the first resistor, the second resistor and the third resistor.
