A Real Life Maths Puzzle

Here's a challenge to any of you up to it. It's a Puzzle, but it's an actual real one, in my actual house.

My house is a townhouse, and it has three floors.
There is a hall on each floor with a light in it.
Each hall also has a three-switch array that controls all the hall lights: { BOTTOM, MIDDLE, TOP}
At the moment, all the lights are OFF.
The current position of the switches is this:

• TOP FLOOR:  {  1 , 1 , 1  }
• MID FLOOR:  {  1 , 0 , 0  }
• BOT FLOOR:  {  0 , 1 , 1  }

Still with me?

OK, what I want is for all the switches to be set such that 0 = off and 1 = on.

Is this possible? How do you do it?
