Abstract
The invention relates to a moving contact which has a sliding contact for the transmission of electrical power from an overhead line to an electrically powered vehicle. The overhead line can cause damage to the sliding contact, since the overhead line can be deflected vertically due to the influence of external forces. In order to prevent such damaging effects on the sliding contact, the moving contact is equipped with at least two height adjusting components. According to the invention, at least one passively sprung component and at least one component whose height can be controlled are installed between the electrically powered vehicle and the sliding contact.
