Contact element for use in frictional contact to switch electric motor or generator, has brush comprising wear segment on which application surface of brush is applied against path, where segment is independent of wear of brush against path

The element (105) has a brush (120) supported against a contact path (110), and an elongated fixing element (125) comprising a fixing segment (160) and a holding segment (170) to receive the brush. A spring element (165) presses the brush against the contact path, so that an end of the brush elongated from the path joins the path according to a bent curve (155) when the brush is used by friction by the path. The brush has a wear segment, on which an application surface (135) of the brush is applied against the path, independent of wear of brush produced against the path. Elément de contact (105) pour contacter un chemin de contact (110), comprenant un balai (120) pour s'appuyer contre le chemin de contact (110), un élément de fixation (125), allongé ayant aux extrémités opposées, un segment de fixation (160) et un segment de maintien (170) pour recevoir le balai (120), et un élément de ressort (165) pour presser le balai (120) contre le chemin de contact (110). Le balai (120) présente un segment d'usure le long de la courbe (155) sur lequel la surface (135) du balai (120) s'appliquant contre le chemin de contact (110) est indépendante de l'usure déjà produite du balai (120).
