Aside from the big nut there are two small bolts on either side, loosen these and you will be able to rotate the unit forward and back.
Have someone put the transmission in reverse, and stand in the rear of the car ( wheels blocked of course ) make small movements with the switch with the big nut as the pivot ( may need to loosen slightly ) and have your helper tell you when the lights are on, hold it steady and tighten the bolts on either side.
I actually recommend that you remove the switch completely while you are down there and clean it out on the inside, then cover it with some new dielectric grease. This switch should probably never need replacing if you can do these two things.
