A dimmer switch has a special resistor that allows a varying amount of current through in order to provide a variable wattage to the output. It is called a dimmer switch because it is often used in lighting circuits to allow the lights to be set to different levels of brightness. Only use volt rated lights and switches when installing a double pole dimmer switch. Two hundred and forty volts can seriously injure you; do not work on a hot circuit. Unscrew the cover plate over the electrical junction box where you are going to install the dimmer switch. Use only a double pole dimmer switch that is rated to handle the wattage required by your light fixture. Add up the wattage of all the bulbs in the fixture to determine the maximum wattage required. Locate the two white wires common wires , the two black wires hot wires , and the two ground wires either bare wire or green insulated. Locate the two chrome screws on the switch they correspond to the white wires , the two brass screws correspond to the black wires , and the two green screws they correspond to the ground wires. Screw the wires to the corresponding terminals.

Single-pole switches are the most common light switches in a home. They have two screw terminals plus a ground screw. One screw terminal is for the “hot” wire that feeds the switch from the power source.
What does single pole mean on a light switch? US Single-pole switch In the US, the standard “single-pole” light switch is single-pole single-throw, with only 2 terminals. The standard US “3-way” light switch used for switching a light from two different swit…ches is single-pole double-throw. It has 3 terminals hence the term “3-way” , and it connects one of those terminals to either of the other two, depending on the switch position.
There’s no OFF position, so the switch has only two positions. MORE How do you hook-up or wire up one light with two on-off switches? For information on how to hook-up one light with two on-off switches, see the Related link “How to wire 3-way and 4-way switches, including wiring diagrams”, shown below. When using the correct size wire, there are severa…l possible configurations of power connection, lighting outlet, and the two 3-way switches.
Power can come from the panel to one switch or the other, or to the light, whichever is convenient. The light can be physically positioned between the switches or at the end of the two-switch series. Each configuration requires different handling of the hot, switched travelers, and neutral wires. In every case, there are runs that require three parallel conductors, whether for neutral, hot or travelers, not including any grounding wires. A 3-wire cable is highly recommended for this application.
How To Wire Single Pole Light Switch with Pilot Light
The original switch was extremely old, and used quick-install terminals ONLY. Even worse, whoever installed it shoved both hots into one port, and both neutrals into another port. None of them were labelled, and there were no colored screws to go by.
Mar 09, · A double-switch allows you to operate two lights or appliances from the same location. Double switches, sometimes called “double pole,” allow you to separately control the power being sent to multiple places from the same switch. For example, you might want to turn on a Views: K.
Jun 20, , The light inside switch has to have a neutral. The fact that there is a red wire in this switch box at all leads me to believe that there is no neutral. It sounds like this is a three way switch box. The question is was the white wire hooked to the switch that you took out. If it was hooked to the switch that you took out then it is part of a three way switch system. Also does this switch work in conjunction with another switch?
If it does then it is a three way switch.
How to Hook Up a Home Light Switch
I have a single pole light switch along with a fan rheostat switch. At the connection box on the ceiling there are 4 wires; the ground, the black, white and red. On the fan light there are blue, black, and white plus green for ground. I will wire ground to green, blue and black from the fan to the black incoming, and the fan white to incoming white. This electrical question came from:
1. Install a single-pole light switch by connecting the black wire entering the box to the bottom, brass-colored screw and the black wire leaving the the box to the top, brass-colored screw.
The first function directs power to the left front and left rear light to signal the intent to turn that way. The opposite pair is energized to indicate a right turn. A flasher in the power supply wire cycles on and off to create the flashing light effect. The second function served by these lights is the flashing of all four lights indicating that the vehicle is experiencing some kind of emergency situation.
A separate flasher in the power supply to the emergency flasher switch causes the lights to flash when energized. The third function is illuminating of the two rear lights to indicate that the vehicle is stopping. A switch activated by hydraulic pressure or mechanically by the motion of the brake pedal sends power to the rear lights. The three functions are performed by separate systems with their own activating switches but use the same four wires to the four individual lights.
If your vehicle has a stock steering column or one equipped with turn signal mechanisms then you simply follow the wiring diagrams making the connections to the turn signal connector and other switches. However, if your vehicle is not originally equipped with turn signals or has a roadster column without turn signals then there are alternative systems that can be installed.
I have a Flaming River roadster column in my roadster and ordered it without turn signal mechanisms. I still want the added safety benefits that turn signals offer so I looked for alternatives.
How to Wire a Double Pole Dimmer Switch
When wiring a switch, there are two scenarios: The tools you need are basic: Leave yourself enough slack. Make a shallow cut about 2 in. Now grab both black and white conductors, and pull them apart in opposite directions so that the jacket rips, continuing until the tear reaches the inside of the box. Stripping the jacket with a knife is trickier.
If the switch has On and Off embossed on its body and it’s the only switch that controls lights or receptacles, it’s a single-pole switch. To replace this kind of switch, follow these steps: Turn off the power to the switch at the main circuit breaker or fuse panel.
Read the following carefully before attempting installation. It is best to mount the converter upright, not upside-down or side-ways as shown here. The single-phase neutral wire is not required for operation of the converter. Properly ground all electrical equipment. Use a grounding clip to attach the ground wire to the conduit box. Resistive or single-phase loads must only be connected to lines A and C.

Failure to do so would cause excessive heat in the wiring and switch and create a risk of fire. This is caused by the amount of power being drawn by the high output lights or accessories. A relay works by using a switch to run 12 volts to the relay. The relay acts as an electrical switch that activates and draws power straight from a good fused battery connection and sends it to the lights or accessory. The power actually going to the switch never gets routed to the lights.
Generally you’ll have a larger gauge wire going to the lights than to the switch because the lights pull much greater power.
Single pole light switches are the most common switches found in homes. A single pole switch controls a light or lights from one location. Single pole switches have two screw terminals, and some single pole switches also come with a green screw for the ground wire.
With power on, remove the cover from the switch and turn the switch off. Using a voltage detector see picture below , place it next to the terminals on the switch. See if there is voltage at one of the switch terminals. If the tester detects voltage, turn the switch on and see if voltage is detected at the other switch terminal. One terminal line will always have voltage and the other will have voltage only when the switch is on. If you only detect voltage at one terminal when the switch is toggled, the switch has probably failed.
Sometimes the switch terminals are connected to the back of the switch, and voltage cannot be detected while the switch is inside the electrical box. In this case, proceed to step 3. Turn off power to the switch at the circuit breaker.
