Abstract
A joystick controller for generating analog signals representative of coordinate positions is characterized by a pair of members movable in orthogonal directions by a handle. Each member carries at least one wiper contact adapted to slide linearly along an associated linearly extending resistor carried on a circuit board to generate the signals representative of coordinate positions. The use of linearly extending resistors for generating the signals, as compared with rotary potentiometers, provides for a reduction in size of the joystick controller, economies in its manufacture, and a high degree of linearity between handle positions and the signals generated.
