ABSTRACT:
A control box is provided having a control shaft which projects from the box and is adapted to be connected, directly or by linkage, to the accelerator pedal of a battery-operated motor vehicle. Connected to the inward end of the control shaft is the movable arm of a potentiometer which is moved angularly to change the circuit resistance when the accelerator pedal is depressed. Mounted on the control shaft are a pair of cams, the followers rollers of which actuate a pair of microswitches which control a solid-state control system which controls the current delivered by the battery to the traction motor of the vehicle.
