A:Let's start with the switch. The first switch controls the light and is linked to the second switch which is called a 3-way. It allows the two switches to control the same light fixture. And that's good. Line voltage track lighting is wired to an electric box just as any other light fixture. For your purposes I would suggest you limit your system a single circuit. You can use a wide variety of light fixture affixed to the track from directional to pendant lights.
