∙ 16y agoA 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.

Light switch connection is usually straight forward. Find your incoming hot wires, black and white. With the switch in the off (down) position and the power disconnected , connect the black wire to the top screw of the switch. Find the load wires and connect the black to the bottom screw of the switch. Connect the two remaining white wires together with a wire nut and push them to the back of the switch box. Install the switch into the wall box, replace switch plate cover. Turn the breaker (power) back on. Flip the switch to the up position and the light should come on.

∙ 12y agoI assume that you have an un-switched Hot (Black) and neutral (White) power in a box where you want to put a light (1st light) and two other lights you want powered by a single switch. Run a Romex cable with Black, White and Bare lead (14 gauge for 15 A circuit or 12 gauge for a 20 A circuit) to the switch. At the powered light connect the black wires together with a wire nut. Don't connect any light wire. At the switch connect the black wire you ran to one side of the switch and the white wire to the other side of switch and wrap black tape around the white wire to identify it as hot. Connect the bare wire to the green screw on switch.
At the 1st light connect the black wire from the switch to the black HOT power wire. Wrap black tape on the white wire from the switch and connect to the black wire on the light and a Black wite to 2nd light and connect all these together with a wire nut. At the 1st light connect the White wire from power source to the white wire on the light and the white wire going to the 2nd light. Wire together all the bare wires in light 1 box.
At second light run a romex wire to 3rd light and connect all the black wires together (3 wires) and all white wires together (3 wires) and the three bare wires.
At the 3rd light connect 2 black wires together and the two white wires together. Some older lights may have two black wires. If this is the case it doesn't matter which of the two light wires you designate as "White", just pick one.

∙ 12y agoA light switch wiring is simple. You just need to contend with three wires. For typical home wiring you would have a hot wire (black), a neutral wire (white) and a ground wire (bare or green). You switch only the hot wire.
The hot wire from the supply side is connected to one terminal of the switch. Connect the hot wire for the load to the other side of the switch. Connect the white wires together with a wirenut. The ground wire is connected to the ground terminal of the switch. This is often connected to the supply and load grounds via a pigtail wire and a wirenut connecting three wires together.

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)
Light switch has 4 wire colors red and white and green and black which is the hot wire?
You have a 3 way switch. Your black wire is the hot wire. Your green wire is the ground wire. Your red and white wires go to the light and other switch. You should have gotten a wiring diagram with your switch.
How do you connect multiple lights to one switch starting at the light?
You put switch in series with the black supply wire and the black wire to the first light. Then connect black wire of first light to black wire of second light, black wire of second light to third light and so forth. Do the same with the white wires and ground wires.
Can you connect a wall switch and a light fixture to an existing light fixture?
If the question is, can I wire a switch to an existing light fixture (and I must assume that it's something like a pull-chain light fixture), the answer is yes.If the question is, "how do I wire a switch to an existing light fixture that has no external switch", the answer is, "in series".The attached web site gives simple instructions on how to wire a basic light switch to an existing light.See sources and related links below
Can you straight wire your cooling fan to a light relay?
Just wire it to a toggle switch. When you need it, just flip the switch.
How do you wire a light and switch with the 2 wire old romex?

When a light switch is turned on what travels through the wire?
Current flows through a wire when a light switch is turned on.
Light switch has 4 wire colors red and white and green and black which is the hot wire?
You have a 3 way switch. Your black wire is the hot wire. Your green wire is the ground wire. Your red and white wires go to the light and other switch. You should have gotten a wiring diagram with your switch.
How do you wire 2 light to the same switch?
by a parellal current switch.
How do you install a dimmer to a light installed with W wire B wire and ground W running into the switch box if the switch box has power from B wire W wire and ground?
If you have one wire into your switch box for your light. this is called a switch leg, the dimmer should be wired across the black and white wire wires.
What causes parking brake indicator light to stay on Pulled wire off the switch and still on vehicle is 98 dodge durango?
The switch probably turns the light out when the switch makes connection, then the light is on when there is no connection (like when the wire is not connected.) Reconnect the wire and push the switch to see if the light goes out. The switch is most likely out of adjustment or bad.
How do you connect multiple lights to one switch starting at the light?
You put switch in series with the black supply wire and the black wire to the first light. Then connect black wire of first light to black wire of second light, black wire of second light to third light and so forth. Do the same with the white wires and ground wires.

How do you wire a light switch in Australia?
you don't it is illegal
Can you straight wire your cooling fan to a light relay?
Just wire it to a toggle switch. When you need it, just flip the switch.
How do you rewire a wall switch to control both ceiling fan and light. The switch currently furns the fan on and off but the light has to be controlled with a pull chain?
Open up the ceiling box and disconnect the blue wire coming from the light and connect it to the black wire coming from the fan. Be sure and put a wire nut on the wire where the light was connected before you removed it. The wall switch is controlling power to the wire where the fan is connected so when you connect the blue fan wire to that connection you will be sending power to both the fan and light from the wall switch.
