Wiring a single pole or one-way light switch is easy, it requires 3 wires. Two black or hot wires, and the earth cable. Just draw the cables from the distribution board (DB) or junction-box, connect the black wire to the dimmer or switch, and then to the bulb. Draw the earth or grounding wire straight from the DB to the switch and then to the bulb.
How to properly wire a three way switch?
This is how the cables are connected:
- The hot source (of the first 2-wire cable) is connected to the common terminal of the first switch (to the left, in the diagram).
- Neutral (or white wire) coming from the same 2-wire cable is connected to the first light. ...
- The ground wire gets connected to the ground screws of both switches and light fixtures.
Can a 3 way switch be used in place of a single pole switch?
Yes it can work. 3-way switches are spdt (single pole double throw) with 3 screw terminals, and regular switches are spst (single pole single throw) with 2 screw terminals. Just pick the correct two contacts and you are good to go.
How to troubleshoot an improperly wired 3 way switch?
Test a 3-Way Switch
- Turn off power to the switches at the circuit breaker and using a tester, make sure power is off. ...
- Using a continuity tester, check continuity between the common (black) terminal and each of the traveler terminals (brass colored) of each 3-way switch.
- There should be continuity between the common terminal and only one of the traveler terminals. ...

- Install the Correct Electrical Boxes. Before you can install your new three-way switch, you’ll need to put an electrical box in to accommodate it.
- Run New Cable (Romex) Between the 3- Way Switches. ...
Can a single pole switch have 3 wires?
The switch in question is a single pole. From it, there is 3 wire cable that leads to a light which then connects to other lights controlled by their own switches. There's no three way set up and this isn't a switch loop either.
Why does my light switch have 3 wires?
A 3-way switch makes it easy to turn on a light fixture from two separate locations in the home. Wiring one is slightly different from wiring a single-pole switch. In a standard, single-pole switch, one light switch controls one light fixture—on/off.

What are the 3 wires on a switch?
With a three-way switch, three wires connect the pair of switches—two black “traveler” wires and a third “common” wire. When the circuit's power is turned on, any of these may be “hot,” depending upon how the switches are toggled.

Does it matter what wire goes where on a light switch?
In the case of a single-pole switch, these wires are interchangeable—it doesn't make any difference which wire is attached to which screw terminal. Inside the switch is a metal pathway that closes when the switch is in the ON position and opens to interrupt the flow of power when the switch is turned OFF.
Can I connect red and black wires together?
These wires are typically used for switch wiring as well as the interconnection between smoke detectors hard-wired into the power system. You can link two red wires together, or you can link a red wire to a black wire. Since red wires conduct current, they are considered hot.
What happens if you wire 3-way switch wrong?
If you don't correctly connect this wire, then your lights won't work from more than one switch. Grounding the switch: You'll also need to locate the ground wire and connect it to the switch too.
How to make a half moon wire?
Bend the ends of the wire into a half moon shape to go around the screws. First, tighten the bare copper or green wire to the green ground screw. Next, connect the two black wires to the remaining brass colored screws. Always tighten the half moon shape towards the right and in a clockwise motion.
How to remove a switch cover plate?
Remove the Existing Switch (If Necessary) Remove the switch cover plate by removing the two screws. The switch is now exposed. Remove the two screws holding the switch in place and carefully pull out the switch. This is the time to take the tester once more and triple check to see if the circuit is off.
Can a broken switch short out?
Broken switches can short out, leave you susceptible to live parts and increase the chance for electrical shock. As with any electrical repair you may perform, safety should be your number one concern. Turn off the circuit you will be working on and double-check it with a circuit tester or voltmeter.
