I am looking at installing a switch for my fog lights and have found the correct switch but have always wondered what these two switches do here. Nearly every ST ( rep and genuine) seem to have them and I feel I’m missing out!
I’m sure somebody can tell me what they are for but I’m guessing it’s a dual fuel pump thing?
Strangely after years of pontification, I've just received a new wiring loom from Jan at http://www.raceservice4u.com in Belgium to finally connect my two dash switches to a pair of 8 pin CDI boxes.

Not really. The pumps are located above the tank so don't get any benefit from gravity. ( regular one pump installations are located low down from the fuel tank) Both pumps feed into one small fuel pipe which has a finite fuel flow capacity. Additionally, the fuel console has a regulatory influence on fuel flow. Any unused fuel not utilised by the MFI pump
(presumably the same principle in carb application) returns to the fuel tank.
