The upper plate has been folded up to show the underside. Each pushbutton has a yellow wire bringing power from the transformer and a black or white wire leading to one point motor solenoid.
To take account of the fact that a double slip, unlike a normal turnout, has no definitive straight or curved branch, a convention was needed to assign one direction to one pushbutton regardless of which branch the train was coming from and depending only on which it was going to. I decided simply to set the point blades to the inlet or outlet track that led nearer to (black button and wire) or further away from (white button and wire) the operator (in practical terms, towards the operating well or towards the walls of the room).
Those posts towards the centre support the upper plate.
