With a standard single-pole dimmer, a single switch controls the light. 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.

Just so, what does single pole mean on a dimmer switch?

Essential switches The most common household switch, a single-pole, has two terminals and simply turns power on or off. A three-way switch has three terminals; a four-way has four. A dimmer switch controls a light's intensity. Usually you can replace any single-pole switch with a dimmer.

Similarly, do I need a single or double pole socket? Haven't read all the other replies dude but double pole completely isolates the load from the circuit whereas single pole is more of a functional thing. BS7671 requires that only the live is switched in a circuit if its single pole else both live and neutral if double pole.

Correspondingly, what is a toggle dimmer?

Toggle-style switch returns light to a pre-selected light level. The slider adjusts the light to the user's favorite level. The slide also adjusts the light to the user's favorite level. The soft locator light becomes illuminated when the dimmer is in the “off” position, making it easy to find in the dark.

What does a single pole switch look like?

A single-pole switch has two brass-colored screw terminals that are connected to the hot, or power-source, wires. These wires are usually black. In this case, the white wire should have a wrap of black tape on it near the switch terminal to indicate that the wire is operating as a hot wire and not a neutral wire.

What is the difference between a single and double pole switch?

A single-pole switch controls just one circuit. A double-pole switch controls two separate circuits. A double-pole switch is like two separate single-pole switches that are mechanically operated by the same lever, knob, or button. A double-throw switch connects an input terminal to one of two output terminals.

Can a single pole switch control two lights?

A single light switch that controls two fixtures, such as two lights or a light and a bathroom or ceiling fan, can be converted to a double light switch that allows you to operate each fixture independently. If each fixture has a separate cable running to the switch, this is a fairly simple task.

Do you need a special dimmer switch for LED lights?

Because of their circuitry, LEDs are not always compatible with traditional dimming switches. If you'd like your LED to be dimmable, you need to do one of two things: find LED bulbs compatible with traditional dimmers, or replace your current dimming switch with a leading-edge (LED-compatible) dimmer.

What makes a light dimmable?

Most light fixtures will work with standard dimmer switches, including those with halogen and incandescent lamps. LED fixtures, for instance, may work with standard dimmers, but some may need a specialized dimmer. Likewise, not all compact fluorescent (CFL) light fixtures can be dimmed.

Do dimmer switches need to be grounded?

New dimmers have either a green grounding wire or a green ground screw that you'll have to connect to a grounding source if one is available. If testing reveals your box isn't grounded, you can still install the dimmer, but you must use a plastic cover plate and make sure no bare metal parts are exposed.

Does it matter which wire goes where on a dimmer switch?

1 Answer. Unless the new dimmer is specifically marked with LINE and LOAD or similar, it doesn't matter which wire goes to which screw/pigtail in a simple two wire switch or dimmer. DO NOT touch any wire until the power is turned back off, or call an electrician if you are not comfortable making this measurement.

How much does it cost to install a dimmer switch?

The more expensive dimmer switches often include features such as a decorative styles and finish options. It is also important to consider the labor and supply costs that are required to install these switches. The total labor costs for the installation of a dimmer switch range from approximately $58 to $135 per job.

Is it hard to install a dimmer switch?

Difficulty: Beginner Instead of merely turning lights on or off, get a wide range of light by installing a dimmer switch. Most dimmers are designed to fit a standard wall box opening, which makes it easy to replace the switch for any incandescent or halogen light with a dimmer.

Why do I have 3 black wires on my light switch?

If the light turns on, the second black wire you connected to the switch is the switch feed and the unconnected black wire is the feed to the other loads. If the light doesn't turn on, then it's the other way around: the connected wire feeds the other loads and the disconnected wire is the light feed.

Can I connect red and black wires together?

In 220-volt circuits, red wires are the secondary live wires. Like black wires, they can be used in some types of switch legs. It's possible to link two red wires together or a red wire to a black wire.

What is the red wire on a dimmer switch?

Red is the switched lead (or a traveler in a 3-way installation), and is attached to the switched hot going to the light. Red with white is a traveler, used for 3-way installations. In your situation, you'll just cap this one off. Green is ground, and is attached to the grounding conductor.

How do I test a dimmer switch?

Attach one lead of the 110-volt test cord to one of the dimmer switch's black wires. Turn the function switch on your DMM to the AC voltage position. If your DMM is a manually ranging meter, set the range selector switch to the 150-volt range.

Are dimmer switches dangerous?

There shouldn't be any dangers if you use a dimmer that's designed for LED lights. Basically, most modern dimmers rapidly modulate between on/off and is safe for long term use in a low state. A side effect however, is that it may generate RF interference or even an audible humming sound.

Do you need a special dimmer switch for LED?

Use an LED Dimmer switch A standard dimmer switch cannot be used with an LED light as you will never be able to dim the LED light either completely or not very well. LED lights need their own special electronic dimmer switch to have a fully functioning and dimming light.

How do I adjust a dimmer switch?

Just follow these steps:

Switch the light on and set to the minimum brightness.

Turn the light off and on three times, leaving a second in between each press.

The lights will go up and down in brightness to show the dimmer is in configuration mode before going off.

Turn the dimmer fully clockwise.

Use as normal.

How does a dimmer switch work diagram?

The diagram below shows this sixtieth-of-a-second cycle. A modern dimmer switch "chops up" the sine wave. If the dimmer is turned to a brighter setting, it will switch on very quickly after cutting off. The circuit is turned on for most of the cycle, so it supplies more energy per second to the light bulb.

Does a dimmer switch reduce voltage?

Dimmers are devices connected to a light fixture and used to lower the brightness of light. By changing the voltage waveform applied to the lamp, it is possible to lower the intensity of the light output. Modern dimmers are built from semiconductors instead of variable resistors, because they have higher efficiency.
