<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 t he signal sources, which therefrom determines the angles between the sight line s from the transducer to the signal sources and, on the basis of these angles, determines the position of the control member.</p> |
