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 I replace a 4 way switch with a 3 way switch?
The way three way switches work is you start with two three way switches, wired in series. You dont convert anything when you add a 4 way switch. You can add as many 4 way switches between the two 3 way switches as you want to. In the end, any of the switches will change the load to on to off and vice versa.
How do you make a 3 way switch into a 4 way switch?
All you need to do is find the 4 wire that currently runs from one of your 3 way switches to the other. You will need to cut/break this and add the 4 way switch in between. The 4 way switch will have 2 terminals marked IN and 2 marked OUT.

Do all switches need to be 4 way?
A four way switch is a variant of a double pole double throw (DPDT) switch, but again thats not really important. Note that you can have as many four-way switches as you want between the two three-ways at the ends. You dont use five-way switches for four lights.
How many switches can be on a 3 way?
More variations of 3-way (two switch) circuits. More variations of 4-way (three or more switch) circuits.
Is there a 4 way smart switch?
A 4 way smart light switch will work just like a normal 4 way light switch in that you can turn your lighting on or off from multiple locations but it can also be turned off with your phone or by using voice commands with Alexa.
What color wire goes to the black screw on a 3-way switch?
The black wire from the circuit breaker panel gets attached to the black screw on the 3-way switch. The black and red wires from the white cable running between the switches get connected to either of the two brass screws on the switch.
Where does the red wire go on a 3-way switch?
The black hot wire connects to the far right switchs common terminal. Red and blue wires link traveler terminals of both switches. The red wire, which is connected to the first switchs common terminal, leads back to the fixture.
How do you tell if a switch is 3 way or 4 way?
A three-way switch has three terminals; a four-way has four. These control a light from two or three switch locations, such as at the top and bottom of a stairwell, at either end of a hallway, or in a large room with multiple entrances.
What color wire goes to the black screw on a 4 way switch?
The white wire from the power source will attach to the lights white wire. The lights black wire should be attached to the black wire running to the first switch. At the switch the white wire (hot) coming from the light, will be connected to the dark colored screw.
How can you tell if a switch is 4 way or 3 way?
A three-way switch has three terminals; a four-way has four. These control a light from two or three switch locations, such as at the top and bottom of a stairwell, at either end of a hallway, or in a large room with multiple entrances.
What color wire goes to the black screw on a 3 way switch?
The black wire from the circuit breaker panel gets attached to the black screw on the 3-way switch. The black and red wires from the white cable running between the switches get connected to either of the two brass screws on the switch.
Can you put a dimmer on a four-way switch?
Correct, no 4 way dimmers. The 3 way must be at either end of the switch legs, whatever it takes. If the dimmer is desired in a location where only a 4 way switch makes sense, the only solution is to extend the power and double back the switch legs so that it becomes the end.
What happens if you wire a three-way switch wrong?
Finding the common wire: When wiring a 3-way light switch, youll need to find the common wire and connect it to the common screw. If you dont correctly connect this wire, then your lights wont work from more than one switch.
Where does the red wire go?
Red wires are usually used as secondary hot wires. Red wires are also hot and should be clearly marked to avoid the dangers of electrocution. Red wires are commonly used when installing ceiling fans, where the light switch maybe.
What is the common wire in a 3-way switch?
Black wire Black wire: This is a hot wire that carries electricity from the power source to the first switch in a typical 3-way setup. Its also called the “common wire” or the “line wire.” Unless the breaker is off, this black wire is always hot.
Which wire goes on the black screw on a 3 way switch?
Three-Way Switch Wired In As marked before from the original switch, one wire (either power in, or the wire to the light fixture) goes to the black terminal, two wires go to the brass screws, and the bare copper wire (not visible here) goes to the ground screw.
What does a four-way switch look like?
4-way switches have four terminals each with two pairs of travelers (one set usually black and one set usually brass color). A four switch configuration will have two 3-way switches, one on each end and two 4-way switches in the middle.
What is the difference between a 3 way and a 4 way switch?
A three-way switch has three terminals; a four-way has four. These control a light from two or three switch locations, such as at the top and bottom of a stairwell, at either end of a hallway, or in a large room with multiple entrances.
How do you tell if a 3-way switch is wired wrong?
Test a 3-Way SwitchTurn off power to the switches at the circuit breaker and using a tester, make sure power is off. Using a continuity tester, check continuity between the common (black) terminal and each of the traveler terminals (brass colored) of each 3-way switch.More items
