Dimmer Switch Wiring
Electrical Question: How can I wire a dimmer switch for light fixtures?
- I am wiring a new dimmer switch for a pair of pendant lights for above a snack bar.The dimmer switch is going next to an existing dimmer switch controlling a fan and fan lite in the same room.
- I was going to use the power source from that circuit to power the new lights.
- There is only a white and black in the dimmer switch box.
- I am thinking the power source for the fan is coming from the other side of the fan.
- How can I wire the new dimmer switch for the pendant lights using only the two wires in the existing box?
Thanks

Dimmer Switch Wiring Wiring Connections
Application: Dimmer Switch
Skill Level: Beginner to Intermediate.
Tools Required: Basic Electricians Pouch Hand Tools and Voltage Tester.
Estimated Time: Depends on personal level experience and ability to work with tools.
Precaution: Identify the light circuit, turn it OFF and Tag it with a Note before working with the dimmer switch wiring.
Materials: Make sure the replacement dimmer switch has the same amperage and voltage rating as the original switch, and is fully compatible with the electrical circuit, the light fixture and the type of light bulbs being used. The dimmer switch must be rated for the amount of watts that will be controlled.
How to make the Electrical Wire Connections When Wiring a Dimmer Switch
- Dimmer Switch for Additional Light Fixtures
- The wiring for the new pendant light fixtures requires a power source with a neutral wire.
- Electrical Power for the Dimmer Switch
- From what you have described the existing dimmer switch only has an incoming power feed and the switched leg back up the the fan and fan light.
- Locating Power for a New Dimmer Switch
- A power source must be either brought to the pendant lights or to the switch box location so the neutral, hot and ground wire will be available for the pendant lights to operate.

Hi Dave,
Just installed Qty 10 dimmable LEDs in my kitchen GU10s 4W, Now my wife wants me to dim them and I have looked at LED dimmers on the net. I see you need to replace the second two way switch with a slave, but the slave only has two wires? How does my existing wiring correspond with that ie Red common or live, Blue = L1 and Yellow = L2
Many thanks
Alex
I am wiring my basement to have a 3way dimmer switch. Can I use two 3 way dimmer switches to control the same set of lights?
Hi Dan,
Yes. Two 3way dimmers may be wired to control a set of lights. Depending on the brand of switches you select, the switches will be wired as a Master and Slave configuration, or the conventional dual 3way switch configuration.
Thanks for sharing your dimmer switch project with us,
Dave
