A vehicle trim element that includes at least one supporting layer having an internal face and an external face, and a skin having an internal face and an external face. The internal face of the skin covers the external face of the supporting layer in at least one detection area. The supporting layer has a through-orifice extending from the internal face to the external face of the supporting layer. At least one detection element is located in the through-orifice. The detection element is in constant contact with the portion of the internal face of the skin covering the through-orifice of the supporting layer.

This invention relates to a telescopic switch for isolated-phase bus duct, comprising: a first male conductor including a first guide-positioner means (4); a 5 second female lead connector coaxially separated from the first connector which includes a second guide-positioning means, wherein said moving contact is coupled coaxially and in a movable manner to the first conductor, and wherein said moving contact moves to an open position, wherein said moving contact is separated from the first conductor and to a closed position where said moving contact causes a contact between the first male connector and that of a second female connector, through interaction with one another from the first guide-positioner means of the first conductor, the second guide-positioner means of the second conductor and the guiding means of the moving contact.

This invention makes reference to interrupter high voltage air-insulated telescopic disconnection switch with moving contact for supplying pressure, consisting of: a first male conductor comprising a first guide-positioner means internally coupled with such first male conductor via an intermediate section, a plurality of double-sided contact plates peripherally coupled with the intermediate section border; a second female conductor coaxially separated from the first male conductor comprising a second guide-positioner means internally coupled with such second female conductor by an intermediate section; a plurality of double-sided contact plates peripherally coupled with the intermediate section border; a moving conductor consisting of guide means internally coupled with such moving conductor by an intermediate support, being such conductor mobile and coaxially coupled with the interior of the first male conductor, where it moves to an open position, and is separated from the first male conductor and to a close position where such moving conductor causes a contact between the first male conductor and the second female conductor, by interacting among themselves to the first guide-positioner means of the first male conductor, the second guide-positioner means of the second female conductor and the guide means of the moving conductor; a plurality of contact plates peripherally coupled with the intermediate support border of the moving conductor, each of such contact plates having contact means for supplying pressure.
