## How many places can you control a light from using 3-way switches?

two different locations Three-way switches are commonly used to control a light fixture from two different locations. For example, a long hallway or stairway might use a pair of three-way switches at each end so that lights can be turned on when approaching one end of the hall or stairway, then shut off from the other end.

## Can you use a 3-way switch as a 4 way?

When connected properly, youll be able to turn lights on from either of the three-way switches or the four-way switch. In the event that you need to switch lighting from more than three locations, simply add additional four-way switches between the two three-way switches.

## Can you add a light to a 3-way switch?

You can only add a new light in to the location where the existing one is. You have three wires between the two switch locations so you can convert the wiring so that each switch location ONLY operates the light nearest to it.

## How do I add another light to an existing switch?

You can usually install a light fixture between an existing one and the switch by cutting the cable to the existing fixture at the location of the new one, inserting the ends of the cable into the electrical box for the new fixture and pigtailing the new fixture onto these wires.

## Will a light switch work if I wire it incorrectly?

Most electrical outlets (properly called receptacles) today are grounded three-prong outlets. But heres the catch: If you connect the circuit wires to the wrong terminals on an outlet, the outlet will still work but the polarity will be backward.
