Marklin 72730 - Control Box
Control Box with on/off switches (separate circuits).
Four separate circuits can be switched on or off. You can use this box to power/unpower track portions for example.
This box is the new replacement of the 7273 Control Box. The only difference is the hook-ups for the plugs. The new style plugs fit this box.
If you do not want separate circuits, you can also use the 72740 box.
