Abstract

This disclosure teaches apparatus for controlling two crossed proportional setting devices by means of a control stick. The control stick is seated firmly at a right angle on a first swivel axis which is supported in a frame swingable around a second swivel axis supported fixedly in the frame to intersect the first swivel axis in the same plane and at right angles thereto. On both swivel axes there are seated firmly radial extensions on the ends of which wiper contacts brush against strip shaped resistors formed in a circular sector around the first swivel axis. The resistors in their turn are fastened to the supporting frame of the first swivel axis.
