US NEC:
A 3-way switching system is where one light, or a set of lights, can be controlled from two switches. Each switch is a one pole double-throw switch. The incoming Hot feed is connected to the center point of one switch and the load is connected to the center point of the other switch. The two outer poles of both switches are connected together. The load can be turned on or off from either switch. Note that all wires on both switches are considered hot, so none of them may be wires having white insulation. Typically, red and black are used.
A 4-way switching system is where a light or a set of lights can be controlled from three or more switches. The two outer switches are the same as if they were 3-way switches. Each inner switch is a two pole double throw reversing switch with only four connections. It is wired to reverse the two hot conductors that run between the two outer switches. The load can be turned on or off from any switch.

As always, if you are in doubt about what to do, the best advice anyone should give you is to call a licensed electrician to advise what work is needed.
Before you do any work yourself,
on electrical circuits, equipment or appliances,
always use a test meter to ensure the circuit is, in fact, de-energized.

To wire a light fixture with a four-way switch, you will need to have three-way switches at either end and one or more four-way switches in between. The wiring setup involves connecting the hot wire to the common terminal on one three-way switch, then connecting the other terminals on the switches with traveler wires. The power source and the light fixture's wiring will also need to be connected to the switches accordingly. It's important to follow wiring diagrams and turn off the power before working on electrical connections.

∙ 12y agoIf you are intending to use a 4 way switch as a single pole switch this is quite easy. A 4 way switch has 2 pairs of terminals (4 screws); usually 2 are brass and 2 are black. Place the hot wire on one of the brass screws and the switch leg wire on a black screw and you're done.
You may need to test the switch to know what position to place it in for down to be off since this is not self evident on a 4 way switch.

Can you connect a wall switch and a light fixture to an existing light fixture?
Yes, you can connect a wall switch to an existing light fixture by running a new electrical wire from the switch to the fixture. This allows you to control the light fixture independently of the existing fixture. It is recommended to consult a licensed electrician to ensure proper wiring and installation for safety.
How do you add another porch light to an existing switch?
To add another porch light to an existing switch, you can run a new electrical wire from the existing light fixture to the new porch light location. Connect the new wire to the new light fixture, ensuring all connections are secure and following proper electrical wiring guidelines. Test the new porch light to ensure it operates correctly from the existing switch.
How do you wire a 220 volts light?
The light is wired the same as any voltage fixture. Bring the source voltage to the fixture and connect it to the two fixture wires. If you want to control the off-on of the fixture take the source voltage to a switch first and then out of the switch to the light fixture.
How do you connect multiple lights to one switch starting at the light?
To connect multiple lights to one switch starting at the light, you will need to run a cable from the first light fixture to the switch. Connect the hot wire to the switch, along with a pigtail wire to connect to each light. Then connect each light fixture to the pigtail wire to create a parallel circuit. Make sure to follow proper safety precautions and consult a professional if needed.
How do you wire a light and switch with the 2 wire old romex?
To wire a light and switch using 2-wire Romex, connect the black wire to the brass screw on the switch, the white wire to the light fixture, and the white wire to the silver screw on the switch. Make sure to cap the unused wire at both ends for safety. Be sure to turn off the power before starting and consult a professional if you are unsure.

How do you wire in a pull chain switch in a bathroom light fixture?
If you are adding the pull chain to an existing fixture then the pull chain switch should have two wires. Wire nut either one to the hot wire coming in and the other to the black wire of the fixture.
How do you wire a pull switch on a hard wire ceiling light that has no switch?
Two options. Change the fixture to a keyed pull-chain, or add a pull-chain adapter to the existing fixture. Both available from Home Depot and others for about $3.

How do you repair a pull chain switch on a fluorescent light?
To repair a pull chain switch on a fluorescent light, you will typically need to replace the switch with a new one. Start by turning off the power to the light fixture, then remove the old switch by disconnecting the wires and unscrewing it. Install the new switch by connecting the wires as per the manufacturer's instructions and screw it back into place. Test the new switch to ensure it is functioning properly before turning the power back on.
How do you connect a 3 wire fixture to a 2 wire fixture that are connected to the same switch what do you connect the red wire to?
A three wire fixture most likely is one that has two separate loads within it. An example is a ceiling fan with a light fixture. If the three wire is used to separately switch the two loads you have to make a decision as to which load you want to work with the two wire fixture. Once that decision has been made connect the two wire fixture in parallel with the your selected load on the three wire fixture. On these types of installations the three wire fixture is usually controlled by two separate switches in a two gang box. The red and black wires of the three wire terminates on the bottom of either switch. The white wire is connected to the incoming neutral. The top of the switches are paralleled together with the "hot" feeder from the distribution source.
Can you wire a light switch with only one 14-2 wire?
No, you need a minimum of two 14-2 wires to wire a light switch properly. One wire is needed for the power supply, and the other wire is needed to carry the switched power to the light fixture. Without two wires, you won't be able to complete the necessary connections for the light switch to work correctly.
What type of prewire for a ceiling fan light?
The pre wire for a ceiling fan light should be made with a three wire cable. This cable will have a red, black, and white wire as main conductors. This cable will also have a bare ground wire. This wire should be strung between a two gang switch box to the fixture junction box. This pre wire allows the supply to be either fed to the two gang box. From the two gang switch junction box, one side will be used for the light in the fixture and the other side of the switch junction box, itwill be used for the fan portionin the fixture.
How do you hook up an overhead light in the kitchen to a two way switch?
To hook up an overhead light in the kitchen to a two-way switch, you will need to run a 3-wire cable between the light fixture and the two switches. Connect the black wire of the cable to the light fixture, the white wire to the neutral wires, and the red wire to the two switches. At the switches, connect the red wire to the common terminals and the black and white wires to the traveler terminals.
