<p>A control equipment provided with an operator-actuated control member (1) having a transducer (10, 11) that receives signals which propagate linearly between a plurality of signal sources (M1-M4) and the transducer. The equipment has means (10, CU) sensing the directions from the transducer to the signal sources, which therefrom determines the angles between the sight lines from the transducer to the signal sources and, on the basis of these angles, determines the position of the control member.</p> |
