Can you put a dimmer switch on a 3-way switch?

With a three-way dimmer, you can control a light with two switches. You will need a three-way dimmer and a three-way switch. This lets you dim from one location and turn the lights on and off from another. If only one switch controls the light, purchase a single-pole dimmer.

Can you have two dimmers on a 3-way switch?

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.

Where does the red wire go on a 3-way dimmer switch?

The black hot wire connects to the far right switch’s common terminal. Red and blue wires link traveler terminals of both switches. The red wire, which is connected to the first switch’s common terminal, leads back to the fixture.

How many wires does a 3-way dimmer switch have?

In wiring a 3-way switch, there are always two traveler wires that connect one switch to the other. For a 3-way switch setup to work, electricity must be routed through either one traveler wire or the other, and the route depends on whether the toggle switch is in the up or down position.

Why does my 3 way dimmer switch not work?

Part of the problem is that there needs to be the right wiring between the switches. There has to be two hot wires*. There also may need to be a neutral wire, depending on the wiring configuration. You still need wiring between the dimmers that are able to have two hot lines, called followers, as well as a ground wire.

How many dimmers can be on a circuit?

You can only have one dimmer per group. You can put the dimmer at either location, but not both locations. There are “companion” dimmers available from some companies, that allow you to place additional dimmers in the circuit.

Where do the red and black wires go on a dimmer switch?

2 Answers

1. Black is the common terminal, and is attached to the ungrounded (hot) conductor feeding the switch.
2. Red is the switched lead (or a traveler in a 3-way installation), and is attached to the switched hot going to the light.
3. Red with white is a traveler, used for 3-way installations.

Can you put a dimmer switch on a 3-way circuit?

Installing a three-way dimmer switch on an existing three-way switch circuit is not only a simple job, but it will add flexibility to your lighting design and improve the overall atmosphere of your living space.

Which wires do I connect to the dimmer switch?

Connect the ground wire to the corresponding wire on your dimmer. Use a plastic wire cap to secure the two wires after wrapping, protecting the connection and ensuring a tight seal. Next, connect the red wire to the hot lead wire and cap them together.

Can a 3 way switch be used as a regular switch?

Yes it can work. 3-way switches are spdt (single pole double throw) with 3 screw terminals, and regular switches are spst (single pole single throw) with 2 screw terminals.
