I am putting two lights over a straight staircase, one on the 1st floor and the other on the 2nd floor. I want them to be controlled together by 2 3-way switches, one near the bottom of the stairs and one near the top. The stairs run along a wall from the 1st floor to the 2nd floor. One of the lights will be a sconce on the 1st floor at the bottom of the stairs. The other light will be a sconce at the top of the stairs. I can easily connect the light on the 1st floor to the switch on the 1st floor, and the light on the 2nd floor to the light on the 2nd floor. But, given they are on separate floors, how do I connect the two lights together so that they will turn on and off together by either/both switches?
I have another staircase where I will have only one light, controlled by two 3-way switches, one on the 1st floor and the other on the 2nd floor. The light will be on the second floor. How do I connect the switch on the 1st floor to the light?
