How to Wire A Four-Way Switch
You probably have a pair of three-way switches controlling a light fixture, you can increase your level of control over that light by adding a four-way switch to the circuit. While the four-way switch could appear a bit of daunting at first, they really are quite easy to put in. The principle thing you’ve to recollect is: the four-way switch gets installed between the 2 three-way switches. If you’d like so as to add some additional flexibility to your lighting–here is the way to wire a four-way switch.
Things You’ll Need
Wire nuts (connectors)
The first step whenever working with electricity is to always turn the ability off. With a 3-way switch scenario, you can’t depend on just turning the switch off, you may have to turn the breaker off.
Because the four-way switch gets installed between the 2 three-way switches, locate the “traveler” wire that bridges the two switches together.
Cut the traveler wire in half. If you cannot route the existing traveler wire into the new switch box, you will have to install a junction box where you may make your connections and feed two lengths of three-conductor wire to the 4-way switch installation site.
Look at the four-way switch and note that it has five terminals on it: two black, two brass and one green.
Connect the 2 white wires together and secure them with a wire nut. Then, twist the 2 bare copper wires together, leaving one longer than the other, so it may be connected to the green ground screw on the switch. Or you may wirenut the two grounds along with a 3rd piece of ground serving because the pigtail.
Take the black and red wires from one of the cables and connect them to the two black screws, one on each side of the switch. It would not matter which color gets installed to which side.
*Important: Do not connect the black and red from one cable on the same side of the switch; it is not going to work.
Take the black and red from the other cable and connect them to the 2 brass screws. Again, it does not matter which color gets installed to which side, as long as they aren’t installed on the same side.
