  • Patent number: 5824979
    Abstract: An accelerator module comprises a printed circuit board having resistance elements mounted thereon, and an actuator pivotably mounted upon the printed circuit board and having a wiper member mounted upon a first end of the actuator. A rotary input shaft, connected to an accelerator pedal of an electric vehicle, has an input shaft arm fixedly mounted thereon, and the input shaft arm is pivotably connected to a second end of the actuator whereby the structural arrangement defines a mechanically advantaged linkage system whereby a predetermined pivotable movement of the rotary input shaft and its associated input shaft arm translates into an enhanced, enlarged, or magnified pivotable movement of the actuator and its associated wiper member for movement along the resistance elements of the printed circuit board.
