Abstract

See full text

A joystick for generating electric control signals comprises the following components: a housing, an operating rod, a universal joint for the operating rod, sensors and an element acting upon these in a positionally dependent manner. The distance of the element from the sensors can be varied by the operating rod. The sensors are in the form of induction coils through which alternating current circulates. The induction coils, in turn, are each part of an electric oscillatory circuit. It is adequate to provide only two such sensors. The element acting upon the induction coils is an induction body, more particularly, in the form of a spherical part which is rigidly connected to the operating rod. The center of the induction body is spaced from the center of the universal joint. By changing the distance of the induction body from the induction coils, the amplitude, frequency and/or phase of the respective oscillatory circuit can be changed in order to generate the electric control signals.
