How do you wire a dimmer switch to another switch?

When wiring the new switch, you will need to find the common wire. The common wire will be on an easily identifiable screw. You will need to connect this same wire to the common screw on the new dimmer switch. If you don’t locate the wire and connect it properly, the lights will not work from more than one switch.

How do I know if my dimmer switch is live?

Dimmer Switch mechanism. You will find a red and black wire connected to the switch. Both of these wires are live wires when the circuit is reconnected. (see lights and switches) Although there was none there, we have added a red indicator to the black wire.

What is the purpose of a dimmer switch?

The purpose of a light switch is to cut the flow of electricity in the loop by making a break in the line. A dimmer switch accomplishes the same thing, but instead of cutting the electricity all at once, it slowly decreases the flow as you lower the slider.

Why does my dimmer switch make a noise?

If you hook up a really cheap dimmer switch, you may notice a strange buzzing noise. This comes from vibrations in the bulb filament caused by the chopped-up current coming from the triac.

How to replace a dimmer switch with a light switch?

Wiring a Light Switch to Replace a Dimmer Switch 1 You can replace the dimmer switch with a regular light switch, only from what you have described you need to install a 3-way light switch, not a single pole light ... 2 The typical connections are as follows: 3 The black wire to the lone screw on the 3-way light switch.

How do you connect two lights to one switch?

Connect one wire to the first switch in the box and the second wire to the other switch, and connect the black wire from each of the lights to the other terminal on its respective switch. The white, or neutral, wires bypass the switch, so the one coming from the power source and the one from the light get spliced and capped in the box.

What is the Black Wire on a dimmer switch?

Black wire = Power or Hot wire White wire = Neutral Bare copper = Ground When wiring a Dimmer switch circuit, all we want to do is to control the black wire (hot wire) to turn Dim/Brighten the load.

How do you wire a dimmer wire to a light box?

once again letting the dimmer wire extend beyond the cable, by about one-eighth of an inch. Slip-on a wire nut and twist until tight. Repeat with the last two wires, cover them with a cap, and twist until tight. Tug gently on all wire nuts, to make sure they are firmly attached, fold the wires into the box and

Why do my dimmer switches Buzz?

Why Do Dimmer Switches Buzz? One problem thats often encountered with a dimmer switch is that it emits a hum or buzzing noise. Its most commonly caused by a fault in the switch mechanism, or, more commonly, in the light filament.

How does a light bulb dimmer switch work?

Old-style dimmer switches worked by interrupting the flow of electrical current passing from the switch to the light bulb by means of a variable resistor. The result is that the light bulb appears dimmer, but it actually takes more electrical current to divert the current through the resistor.

What are the most common questions about dimmer switches?

Here are answers to the most common questions about dimmer switches. The Problem: The dimmer switch is buzzing or humming. The Solution: Update your dimmer rating. When humming or buzzing is coming from the dimmer itself, that may be a sign of an overload.

Why is my light switch making a humming noise?

A hum that comes from the switch itself means that it is old, or cheap, and cannot handle the increased voltage. If it is a noisy switch, try lower wattage bulbs that won’t overload it. You may also want to consider the combined wattage from multiple bulbs, in a lighting piece such as a chandelier. Remove a bulb or two and see if the hum reduces.
