METHOD AND ARRANGEMENT FOR TRANSFERRING ELECTRICAL POWER AND/OR INFORMATION SIGNALS

摘要

The present invention relates to a method and arrangement for transferring electrical power and/or information signals between a first structure and a second structure, said structures being mutually movable by means of a driving support element. The method comprises the steps of providing an transfer element arranged to transfer electrical power and/or information signals between the first structure and the second structure, and controlling electrical contact by means of the transfer element so as to provide electrical contact in at least two different contact areas, said contact areas corresponding to predetermined mutual positions of said structures.
