The switch connects the cable to a DC power line in one state, and insulates cable and sets the line to ground or to another line in another state. A voltage sensor (PP`) recognizes the voltage conveyed by the cable, and a protection unit (PFC`) to protect against lightning and shunting impacts. An independent claim is also included for a current collecting system for railway rolling stock comprising a multi-function device.",
