Abstract: Method for installing a cable into a duct, comprising the steps of: determining a maximum pressure, setting a leaking mode of a leaking plug to start at a leaking pressure drop equal to or lower than the maximum pressure, attaching the leaking plug to a foremost end of the cable, introducing the foremost end of the cable into the duct, supplying a pressurized liquid into the duct: at a supply port, and at a supply pressure, so that the cable is pulled by the leaking plug, before the foremost end has reached the second extremity, exceeding the leaking pressure drop at a location close to the leaking plug.

Abstract: Arrangement for mounting an electronic display (30) at the centre of a rotary switch (12), including: a support board (18), an electrical connection device (74) which is arranged on the board (18) in order to connect the display (30) to an electronic control circuit, a cylindrical box (32) which is mounted on the board and which forms the fixed central body of the rotary switch (12), an annular body (34) forming a rotor which is mounted in rotation on the cylindrical box about an axis so as to form a turning part of the rotary switch (12), characterized by the fact that the cylindrical box (32) includes a container designed to receive the display (30) by transversal insertion, relative to the axis of the rotary switch (12).

Abstract: A control device, in particular for a motor vehicle, including a rotary switch and a peripheral display zone which are arranged on a board and which are back-lit by a back-lighting device, the rotary switch including a knob which is mounted in rotation relative to the board about an axis, the knob being provided with an illuminated pointer turning with the knob, the peripheral display zone including fixed illuminated symbols arranged around the rotary switch, characterized by the fact that the back-lighting device includes at least one light source which cooperates with a light guide lighting both the illuminated pointer and the peripheral display zone.
