Magnetic electrical connectors are fitted through small holes drilled in the base section of the traverser, these holes were marked when the first two track sections were fitted.
There are two magnetic terminals for each corresponding section of layout track, in this case four in total. Cork board adds cushioning support.
From the mains powered controller, the single positive and negative DC wires are split into two pairs and connected to an on/off toggle switch each. From each switch they are split again into two independent pairs via a connecting block, firstly to the fixed track (prewired fishplates) and secondly to the magnetic terminals, again via a connecting block.
