A battery-charging contact consists of a contact plate, which is mounted on the floor in the track of the FTS or, in some cases, also to the side, and a current collector, which is mounted on the FTS. Power is supplied to the contact plate on site by a charging device. The contacts are activated by the central computer of the FTS in the charge position. The contact plate, used for floor contact, is equipped with diagonal run-on surfaces, which enable a relatively smooth, low-wear travel of the spring-cushioned current collector.
