I have a 126 box on a Fiat 500 and it seems that the way the switch should operate is to be normally closed, ie. when reverse is selected it releases the previously depressed plunger on the switch and in the contacts are made. The switch I have been supplied does the opposite, meaning that I would have a reversing light all the time except when reversing.
I wonder if anyone here has encountered this and can suggest a part number or supplier for the correct switch?
