Can a dimmer be put on a 3 way switch?
A multi-location dimmer allows you to control the same light fixture from multiple locations. Instead of using just two switches, you can use as many switches as possible in any combination of single pole and 3 way switches.
Can a 3 way switch have a dimmer on both ends?
3-Way Dimmer Switches When using a 3-way dimmer switch, you should only have one dimmer on the circuit. The other switches (you can have more than one) must be on-off switches only. In this setup, the light level is controlled from a single location, whichever light switch you replace with the dimmer switch.

Can I put a dimmer on any light switch?
Most light fixtures will work with standard dimmer switches, including those with halogen and incandescent lamps. Determine whether your fixture uses line or low voltage. If you install line-voltage track and rail lights with incandescent bulbs, you can use dimmer switches to control their brightness.
How many dimmers can be on a circuit?
There is no limit of how many dimmer switchers you can fit in one circuit. You can also have two dimmer switches operating one light.
Does a dimmer switch require special wiring?
Dimmer switches don't need special wiring at all. Single-pole dimmer switches can just replace existing single-pole light switches, and 3-way dimmers can easily replace a standard 3-way switch or be used as a single-pole switch with one wire capped off.
Do dimmers need a neutral?
If the light is off, without a neutral you won't have a complete circuit to power the smart dimmer circuitry.
Why does a dimmer switch have 3 wires?
A 3-wire NM connects the travelers of the dimmer to the travelers of the 3-way switch. Traveler wires are interchangeable on each switch. The 3-way dimmer and 3-way switch are also interchangeable. The common terminal of the 3-way switch connects to the light fixture(s).
Can you have 2 dimmers on a 2 way switch?
Traditionally, you cannot dim a light from two different switches, as it will cause a conflict in the circuitry. Any electrician will tell you that this will not work for a regular double switch three-way circuit. However, you can set up specialized two-way dimmers using a primary and standby switch.

How does a companion dimmer work?
If the lights are on 100% power the companion dimmer will dim the lights to about 50% the first time it's pressed. Then will continue the behavior of only completely turning out the lights for the split second it's pushed or if holding the button.
Can you put a dimmer switch on a two way switch?
If you have a 2-way circuit (where the same lights are controlled by two switches) you must choose a push-on/push-off dimmer and replace one of the switches with that dimmer. You can only use one push-on/push-off dimmer in a 2-way circuit. It must be used in conjunction with a normal switch.

Installing Two 3 Way Dimmer Switches
3 Way Dimmer Switches and Compatibility [ad#block] Electrical Question: Is it possible to have two three way dimmer switches? I want to know if its possible to put two dimmer switches on one light. I really would like to see a diagram of it where the dimmer will be on the end of the circuit.
Where is the red wire on a dimmer switch?
In most wiring applications, the red wire is connected to the single screw on the left side of the switch.
Which way should the switch be facing?
Position the switch so that the side with the two screws is facing your right.
What is a dimmer switch?
Some dimmer switches are set on a 3-way switch. This means that the lights can be turned on and off from the dimmer switch as well as another light switch . These types of switches are common in hallways and staircases. They are often found in large rooms as well.
How many watts does a dimmer switch need?
The maximum wattage for those fixtures is 300. That means that your new dimmer switch will have to be able to handle a load of 300 watts.
What wire is the hot wire on a dimmer switch?
Next, the Hot wire (black) from the panel needs to be connected to the black wire on the dimmer switch, and the red wire from the 3-wire cable is connected to the red wire on the dimmer switch while the remaining black wire is connected to the last wire on the switch.
What is the black wire on a second light switch?
Finally, at the second switch, the black wire from the light fixture is connected to the common terminal while the remaining black and red wires from the first switch are connected to each of the remaining terminals on the second switch.
What is the ground wire on a switch?
The ground wire is what prevents stray current from electrocuting your family and possessions. The ground wire is often white, green, or bare.
What wires should be connected to the white wires in a second switch?
The Neutral (white) wires from the power source cable and the outgoing feed (a 3-wires cable) should be connected together as in the second junction box containing the second switch where the white from the light fixture should be connected to the white from the first switch.
What to do if you don't check both lights?
Before you put up your tools and tidy the work area , you need to make sure that the lights work from both light switches. If you fail to check both switches, you may find that one of the switches doesn’t work. If that is the case, you will have to pull your tools out and remove the switch to determine the problem.
What happens if you replace a three way switch with a dimmer switch?
If you simply replaced one of the three-way switches with an ordinary dimmer switch, it would no longer toggle from one line to another and would only go on or off and reduce the power of the current. The top of the stairway, bottom of the stairway reversing control would no longer work.
Why do multiple dimmer controls talk to each other?
New multiple dimmer controls are more expensive, but they talk to each other to allow controlling the intensity of a single light from multiple locations.
Why do three way switches have three screws?
That is why the three-way switch has three screws on it. One is the common wire and the other two carry that common current to one line or another. In fact a three-way switch all by itself would be of little use for your light. It takes a pair of three-way switches as shown in the diagram to cause that re-routing of electricity ...
How to reduce the power of a light?
What you could also do is to put a dimmer switch on the common line leading into a pair of three-way switch. This would turn on and off the whole system, as well as have the possibility of reducing the light level. If you put one dimmer switch on each end, outside of each of the three-way switches, you would have to have both dimmers on and the end result would be a reducing of the power of the light by the sum of the two dimmers, so if all you want to do is to reduce the strength of the light, use just one dimmer.
Can you put a dimmer switch on each end?
If you put one dimmer switch on each end, outside of each of the three-way switches, you would have to have both dimmers on and the end result would be a reducing of the power of the light by the sum of the two dimmers, so if all you want to do is to reduce the strength of the light, use just one dimmer. All of that is to say that ...
Can a dimmer switch be used on a stairway?
All of that is to say that a simple dimmer switch cannot give you that top of the stairway, bottom of the stairway control, but can be used to reduce the intensity of the light, but you will have to remember to leave the dimmer on at all times for the rest of the system to work.
Dimmer and 3-Way Switch Setup
- First thing’s first you have to make sure that you’re using 3-way dimmers. If you use an ordinary dimmer switch, the other 3-way switch would lose its functionality. Now that that’s out of the way, let’s get to the main topic. If you’re using a normal 3-way dimmer, you can have only one dimmer. The switch at the other end must be a 3-way switch. You would be able to turn the light on/off fr…
