Abstract
The mechanical cable control, including an automatic adjustment device (4, 5, 9/7) between a first portion (2) of the shielding conduit of the cable and an outer ferrule structure (6) comprises at least one electrical path mechanism (I; II) incorporating a pair of cooperating electrical contacts (12, 11; 12', 11'), attached to the outer ferrule structure (6) and, via a disengageable connection, to an extension of the first conduit portion (2). The cable control typically incorporates a pair of contacts (11, 12) for detecting the operation of the control and a pair of contacts (11'; 12') for indicating the wear of the component to be actuated (C) by the cable control.
