You can't. You will need a 3way switch at each end with 12/3 or 14/3 wire run between them. Power at one switch and light wire at the other switch.

How do you wire a light with two switches?

Use two three way switches. Hot feed comes to one switch. Wire to light goes from other switch. Two travelers (same size wire as other wires) are needed between the two switches.

Can a single pole switch be used to control one light between two single pole switches?


What does com mean on a light switch?

In a situation where there is only one switch controlling the light or lights you normally use a spst (single pole single throw) switch that has only two connection terminals. This type of switch either connects or disconnects the two wires that are connected to the switch's terminals depending upon the position if the switch lever. The com terminal on a light switch means that it is a three way or the kind of switch used where there are two or more switches that controll the same light or lights. The three way switch is a spdt ( single pole double throw) . If you look closely you will find this designation somewhere on the switch. On the spdt switch you have three terminals, a common and two branches. In one postiion the common connects to one branch and in the second position the common connects to the other branch. If you are trying to install this switch in a situation where there is more than one switch controlling the light you must have the ability to correctly identify the common wire; if you can't do that you need help from someone who can do that correctly.

How do you add another porch light to an existing switch?

Piggyback off the box for the existing light. Run a wire from the existing junction box to a new junction box (which is placed wherever you want the new fixture). Then, in the existing box, connect the wire coming from the switch, the wire for the existing fixture, and the wire for the new fixture together using wire nuts. Wire up the new fixture, and presto, you have two fixtures on a switch where there was only one before.

How do you wire a light switch that has a black common screw and two gold screws one on each side of light switch and a green screw?

That is called a three way switch. It's used in conjunction with another 3 way switch in another area and they both control a light or set of lights. The black is power and the other two are called travelers that wire to the the other 2 gold screws on the other switch. A three way switch can be used as a single pole switch by using the black screw and one of the brass screws. You will have to test the circuit to orient the switch so up is on and down is off, if that is what you desire, because it is not obvious on a three way switch. The green screw is simply your equipment ground. You place your green or bare conductor there.

What is difference between single pole and double pole thermostat?

A single-pole switch is an on/off switch that switches a single wire such as the circuit to your overhead light. A double pole switch is also an on/off switch that switches two wires. You would use this to switch as 240 volt circuit (which requires two hot wires) or if you had two circuit you wanted to switch at the same time. I've used them when I had two large light circuits that required two breakers that I wanted to switch with one switch.

How do you wire a two way switch one controls the outlet the other the outdoor light with a pigtail?

You need two separate switches. You can get two switches that are in the same form factor as a single switch (2 gang switch). You use one switch for the outlet and the other for the light. You switch the black wires which are "hot".

How do you wire a DPST switch?

A double pole single throw switch. used to switch two lines at the same time.

How does a double pole switch work?

A switch is inserted in series with a single wire. When the switch is on, it is as if the wire had not been opened to insert the switch. When the switch is off the wire is open and no current can flow. All a double pole switch does is allows you to switch two separate wires at the same time with the same switch action. A single pole switch just switches one wire.

Can you make a shop light have an on off switch that plugs into a wall outlet?

Sure thing. Cut an extention cord in two. pipe it into an electrical box. Wire the white wire straight through. The black wire goes to the single pole switch. For safety wire the ground both straight through and to the switch.

How do you wire a light with a switch to another light with a switch in a different room?

Search Google with: "two-way circuit" or "two-way switch" and have a look through the websites on the subject.

How do you wire a light switch?

A light switch breaks one half of the circuit to the light. "CODE" says to break the black wire. I usually break the white since this is the ground and should have less chance of a shock from a bad switch. Since it is only half the circuit if you are replacing a switch it does not matter which wire goes to which terminal on the switch. This applies to a single pole switch. A double or triple switch is something else. If a light that turn on from only one place is a single. If it turns on from 2 places, two doorways into a room or top and bottom of stairs it is a two way switch and it does matter how it is wired. Nothing will blow up, it simply will not work from both if wired wrong.

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 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
