How to wire several lights into one switch?

with your power coming into the switch, you connect the neutral wire (white) to the other white wire that is going to the lights. then the 2 black wires go onto the switch. now that you have the light switched, you just connect the other lights to the first one


How do you wire 3way switch with 2 lights powered at one of the lights?

See sources and related links below. For two lights just parallel the feeds from the first light with a two wire cable to the second light.


Where is the 2-wire switch on the brake pedal that opens when depressed and lights the tail lights on a 94 Honda Accord LX Is it under the hard-rubber covering Behind the pedal?

Just follow the brake pedal up until you find a switch that has a little piston coming out of it up againts the pedal arm itself. It may be a 5 wire switch not a 2 wire switch but in any case it the brake light wire that turns on the brake lights will be the wire that changes to hot (12 volt pos) when the peddal is pressed. Hope this helps.


How do you wire two 3-way switches to 5 lights?

Wire the two 3 way switches using 3 wire cable (red, black, white and bare). Then connect the first light to the others using two wire cable (black, white and bare) kind of like a daisy chain. The power goes to the first 3 way switch, then switch one goes to switch 2 using the 3 wire cable (even though it has 4 wires in there), then the second switch goes to one of the lights. Hope that helps.


How do you wire 2 switches on one circuit?

If your wiring it up for a light switch, then you will need 2 3 way switches, this will allow you to turn on and off lights from 2 locations


How do I wire one switch to control two lights with the power coming into light?

Using 14/2 or 12/2 wire, black, white and bare. Bring the hot/black wire in the light down to the switch on the black wire, through the switch and back to the light on the white wire. Connect the white wire in the power wire to the white wire in the light. Connect the white power wire from the switch to the black wire in the light. Run the black and white wires in the first light to the second light. You should wrap the white power wire from the switch with black electrical tape to cover the white so that the next person realizes it is a power wire.


How do you wire a light and switch with the 2 wire old romex?

with a standard 1 pole light switch (one switch operating the light) it is black wire to black wire and white to white (non grounded)


How two wire 2 light switch up in 1 box?

Tie all the white wires together under a wire nut and push them back in the box. Tie the black incoming power wire and outgoing power wire, if there is one, together under a wire nut with a black wire pigtail. Connect this pigtail to one screw on each light switch. Connect the black wire going up to the lights to the appropriate switch you wish to use to control that light.


How do you wire a one light to be operated from 4 location?

you will need 2-3way switch and 2-4way switch


How do you wire multiple lights on a 3-way switch with one between and one not?

Explain in more detail what you mean. What is between: the switch or the light? What are you trying to accomplish with this setup? The term 3-way switch means 2 switches controlling one or more lights. If you have 2 lights and one switch then you need a standard 75 cent switch. Generally with 3-way switches, there are 3 wires not including the ground, black, white and red. some houses attach the white to the switch, some attach the black. Generally the white will feed through the box not attaching to anything but another white wire. The black will attach to the upper and lower screws on one side of the switch while the red attaches to the opposite side. The red goes to the other switch and black goes to the light fixture(s).


Can you by pass the AC pressure switch?

If it is a 2-wire switch- yes If it is a 3-wire switch- no


How do you give two way switch connection?

If I am correct I think you are wanting to know how to connect a 3 way switch where you can turn off an light at 2 locations. At one switch you run a 12/2 wire from the switch to the light. There is no power at this switch. At the other switch you have your a power input wire. Run a 12/3 wire from one switch to the other. Connect all the whites together and shove them back in the box at the switch with the wire going to the light. At the switch with the 12/2 wire going to the light, connect the black 12/2 wire coming from the light to the black screw on the 3way switch. Now connect the red wire and black wire from the wire you ran between the switches to the other 2 screws on the switch. It does not matter which you connect to which screws. Connect the ground wire and put that switch in the wall with the cover on it. Now move the the other 3way switch with the power wire. Again connect all the whites together and shove them back in the box. Connect the black wire from the power source to the black screw on the switch. Now connect the other 2 wires left, black & red to the other 2 screws that are left. Again it matters not which wire you connect to which 2 screws that are left. Connect your ground wire and put the switch in the wall a cover on. At the light connect the black to black and white to white. Connect the ground wire to the green or ground wire on the light. You are done.


Why doesn't the rear brake lights light up but the turn signal lights do?

you may have a faulty turn signal switch may also try to test the brake switch located on the brake pedal with a test light to do this locate the 2 wires on the switch one will b hot the other not with the key on depress the brake pedal and check 2 seee if the one wire that wasnt hot, is now hot if it is then the switch is good good luck cause that turn signal switch is about 300$


How do you make a circuit with 3 bulbs 2 switches and and 2 batteries where the 1st switch controls the lighting of all the bulbs and the 2nd switch controls the lighting of the second bulb?

Connect the two batteries for the voltage needed. If they are 12 volt batteries and the lights are 12 volts, connect the batteries in parallel (negative to negative and positive to positive). If they are 12 volt batteries and the lights are 24 volts, connect the batteries in series (negative of one battery to positive of the other). Run a wire from batteries to first switch, then to two of the lights and the other switch (in parallel). From the second switch run a wire to the third light, then connect all three lights back to the battery.


How do you wire 2 switches to same lights?

This is done using two two-way switches, switches with two switching position. The input live wire from the circuit breaker goes to the middle point of one switch. The output live wire to the light is connected to the middle point of the second switch. The two remaining points from one switch are then connected to the two remaining points on the other switch. The neutral from the light goes straight to the neutral bar in the Distribution Board.


How do you wire a 3 way light swittch?

when wiring a 3 way light switch u have to have a hot side and a switch side meaning switch one out of the two will be fed with your power 120v or 277v/ the hot wire will connect to the black screw on switch one then run 3 wires to the other switch two of those three wires will connect to the other two screws on switch one and will connect to the same two screws on switch two the third wire is ur neutral wire the white wire u have to carry over to switch two just use wire nuts for the white wire ok now the black screw on switch two will connect to the black wire feeding the light and the white wire u carried over will go to the white wire going to the light also. so you will need to run 2 wires down to switch 1 a hot and neutral/then 3 wires from switch 1 to switch 2/and then 2 wires out of switch 2 going to the light,out of the 3 wires u run from switch 1 to switch 2 the white is the only 1 that goes out to ur light together with the black wire that is connected to the black screw on switch 2 hope u can understand this try draw it out as u read it


How to wire single switch to operate 2 lights?

The short answer is to wire it the same way you would to operate 1 light. The second light is simply put "in parallel" with the first light.


From one set of lights to two different switchs?

This requires a 3way switch at each of the 2 locations you want to use to control the light. You will need to run power to one of the switch locations and then run a wire to the light from the other switch location. Run a 12/3 or 14/3 wire from switch to switch. Be sure and use the same size wire you use to supply power and run from the switch to the light. Do not mix wire sizes. If the circuit is on a 15 amp breaker then use 14/2 wire, and if it is on a 20 amp circuit use 12/2 wire. Now you have power at one of the 3way switches. A wire going to the light at the other switch, and a 12/3 or 14/3 wire running between the 2 switches. Starting at the switch with the power supply input connect all the white wires together under a wire nut and push that back in the box. Connect the ground wires together and connect that to the green ground screw on the 3way switch. Use a jumper wire if necessary. Look on the switch and you will see 3 screws. One is black and the other 2 are silver. Connect the black power wire to the black screw. Connect the red and black wires, which are called travelers, to the other 2 silver screws. Does not matter which wires you connect to which screws. Remember you are supplying power to this switch and not to the other switch. The black wire you connect to the black screw is the wire coming from the power wire you brought into the switch box, and not the 12/3 or 14/3 wire you ran between the switches. Now move to the other 3way switch. Connect all whites together and push them back into the box. Connect the grounds together and then connect them to the green ground screw on the switch. Now connect the black wire that is going up to the light to the black screw on the switch. Connect the red and black traveler wires to the 2 remaining screws. Once you install the light, black to black and white to white, ground to ground. Turn on the power and if you followed these directions to the letter you can turn on/off the light from 2 locations.


How do you add a switch to a light fixture?

Install the switch in the wall outlet box you have installed. Now run a 12/2 or 14/2 wire from the switch to the light fixture in the ceiling. Run the exact same size wire that is already powering the light. Connect the ground wire coming from the light switch to the ground wires in the ceiling box. At the light in the ceiling cut the black wire powering the light. Cut only that wire. Now strip the 2 black wires back and connect the white wire coming from the wall switch to one of the black wires and the black wire coming from the wall switch to the other black wire. At the wall switch connect the ground wire to the ground screw on the single pole switch. Now connect the white and black wire to either screw. Does not matter which one. Now when you turn the switch off you are breaking the flow of electricity to the light. This is called a switch leg.


How do you wire 4 lights with 2 switches?

If you want the four lights to come on/off when either switch is operated and you want the lamps to be fully lit then you must wire each lamp in parallel. from the supply wire to the common terminal of the first switch. Connect a wire to each of the other two terminals on the first switch. Conect each of these wires to the similar terminals on the second switch. From the common of the second switch connect a wire to the first lamp. From the other terminal of the lamp connect a wire back to the Neutral source. This will give you one lamp controlled by two switches. Now connect a wire from each terminal of the 1st lamp and connect it to the two terminals on the second lamp. make similar connections for lamps three and four.


How do you wire a outlet to work from a light switch?

Bring power into the switch box with a 12/2 or 14/2 wire and send power from there to the wall outlet with another 12/2 or 14/2 wire depending on the circuit. 12/2 for 20 amp and 14/2 for 15 amp circuit. You will now have 2 sets of wires in the switch box. Connect all the whites together under a wire nut and push them back into the box. Connect all the ground wires together and attach them to the green ground screw on the switch. Connect the black wire from the power source to one of the screws on the switch, does not matter which one. Then connect the black wire going to the outlet to the other screw on the switch. Put the switch back in the box and install the cover. At the wall outlet connect the ground to green ground screw, white wire to silver screw, and black wire to gold screw. Put it in the box and install the cover.


How do you wire 2 light to the same switch?

by a parellal current switch.


How do you rewire a series of electrical switches?

If the switch is a single pull switch there will only be 2 black wires and a ground that need to be connected to the device. If it is a 3-way switch there will be a ground wire, a red wire and 2 black wires (one of which is the common)that need to be attached to the device. a 4-way switch will require a ground wire, 2 black wires and 2 red wires that all need to be hooked to the device.


Is there a way to wire a 3 way household dimmer switch as a 2 way dimmer switch?

You need a three way switch to control lights from two locations. The name is misleading. Three way switch refers to the connection points on the switch. You can use a three way switch as a single switch as long as you place hot wire on the brass screw and the use any of the other screws for the return hot.


How do you wire from breaker to light fixture 1 to light switch 1 to Light switch 2 to light fixture 2?

If you are asking about typical house hold panel, switches and lights then you would get some 12/2 AWG Romex wire and run it to everything. You want to start your taps from the load end (the lights). Tap your neutral, hot and ground to the light fixture 2. on switch 2, tap the hot going to the light to the bottom pole of the switch. next take a piece of black wire only and tap it to the top pole of switch 2 and the top pole of switch one. Then tap the hot going to light 1 to the bottom pole of switch one. tap the 3 neutrals together and the grounds together. tap the hot, neutral, and ground to light 1. lay the neutral wire onto the neutral bar in the panel. Lay then ground wire to the ground wire in the panel. Lay the hot wire to the breaker in the panel. Make sure all connections and screws are tight but do not over tighten. If you do not have good knowledge or in doubt, do not work with any live circuits or in the panel. Electricity kills regardless the voltage or amperage. If you dont know what you are doing call a pro!
