What made it any different then the rear fog switch?
Ed
Ed, I think the front is simple, just on/off, however a rear fog has to pass through some sort of latching relay so that when the car ign is switched off it de-energises the switch, so that when the ign is turned on again the rear fog will not still be on
As posted to Ed on another thread the switches are electrically the same, if indeed not exactly the same.
As can be seen below both front and rear command the BCU to supply the matching foglight(s) whilst increasing their LED icon brightness, but only when headlights are on.
I suspect in each case it's just a momentary switch that as you suggest, latches the foglight on or off.
