Data input device with potentiometer and control stick for piloting an aircraft, the control stick including the data input device

摘要

The device has a potentiometer (10) including first and second fixed connection points (13, 14) respectively situated at two ends of the potentiometer. A third fixed connection point (15) is situated at an intermediate position between the two ends, and a fourth mobile connection point is movable between the two ends. Two resistors (R1, R2) supply a voltage and a current to the potentiometer via the third connection point and a slider (11), respectively, where a voltage difference between the first and second connection points forms a voltage that represents the position of the slider.
