PCT No. PCT/FI97/00168 Sec. 371 Date Jan. 4, 1999 Sec. 102(e) Date Jan. 4, 1999 PCT Filed Mar. 13, 1997 PCT Pub. No. WO97/34353 PCT Pub. Date Sep. 18, 1997A power take-off adapter for a track having a connection slot and current conductors includes locking and contact fingers (8, 9) for connecting the power take-off adapter arranged in the connection slot of the track mechanically to the track and electrically to the current conductors of the track, a switching device (10) that is switched to move the locking fingers to a connecting position in which they protrude from a switching member (5) and to a retracted disconnnecting position. To provide a simple construction, the locking and contact fingers are arranged on the same axle member. A rotary movement of the switching device is arranged to bring all the contact fingers in contact with the current conductors of the track. The power take-off adapter is provided with a selecting switch (11) by which it is electrically connected to the desired phase conductor or electrically disconnected from the phase conductor. |
