ROTATION-TYPE VARIABLE RESISTOR AND METHOD FOR MANUFACTURING SAME

摘要

A rotation-type variable resistor is provided with: an insulating substrate; a resistor pattern and a current collector pattern provided on the insulating substrate; a rotor rotatably attached to the insulating substrate; and a slider attached to the rotor and providing electrical continuity between the resistor pattern and the current collector pattern by being in sliding contact with the resistor pattern and the current collector pattern. The resistor satisfies Z ≤ 4.0 and Z × L < 10, where Z[mm] is the effective maximum size of the resistor pattern as variable resistance, and L[%] is electrical linearity.
