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

摘要

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.
