ABSTRACT:
A device for controlling the amount of resistance in an electric circuit. A variable resistor is fixedly attached to a carriage slidably mounted on a pair of spaced apart guide rods within a hollow frame. A pinion gear is fixedly attached to a shaft of the variable resistor for allowing the resistance of the variable resistor to be varied by rotation thereof. A rack gear is fixedly attached to the frame in engagement with the pinion gear whereby manual lineal movement of the carriage back and forth upon the guide rods will cause rotary movement of the shaft of the variable resistor thereby varying the resistance of the variable resistor.
