With the power coming to the switch and then going to the lights you will notice that there are two black wires two white wires and two ground wires bare wires.
Electrical wiring 2 way light switch.
The three terminals are usually named com l1 and l2 but sometimes com 1 way and 2 way are also used.
Let s assume the load you are controlling is a light.
A three way light switch is one where you have two switches that have the ability to control the same light or set of lights.
Take the white wire leading to the second box and mark its end black too.
If the light switch has a ground screw on it usually green and at the bottom of the switch connect it now.
With this done you can now start to wire the two way electrical switch to the box.
The two way switch will have corresponding wires or screws.
Therefore the 2 switches the light 3 way.
The power source comes from the fixture and then connects to the power terminal.
Connect the black wire coming from the lightbox with the black wire leading to the second switch by twisting their ends together and fastening with a third wire nut.
Wiring a switch loop when the electrical source originates at a light fixture and is controlled from a remote location a switch loop is used.
A 2 way switch wiring diagram with power feed from the switch light.
By wiring a 2 way switch the circuit below shows the basic concept of electricity flow to the load.
You will see that there is a hot wire that is then spliced through a switch and that then goes to the hot terminal of the light.
Connect the 2 ground wires with a fourth wire nut.
There will be an additional wire needed often red to connect the switches together to a dedicated screw or input on the switch that is specifically marked for this purpose.
First of all we should connect the ground wires to the box.
Two way switch can be operated from any of the switch independently means whatever be the position of other switch on off you can control the light with other switch.
This circuit is wired with a 2 wire cable running from the light to the switch location.
Before proceeding an important component called a two way light switch is the main element of the 2 way switching irrespective of the type of wiring used.
A 2 way switching connection means you can control an electrical equipment like bulb by two switches placed at different places generally used in the staircase.
Connect the white wire with the white wire the black wire with the black wire and either splice the red wire with the black wire or attach it to the black wire s source.
The electricity flows from the hot wire black through the 2 way switch shown in off position and then to the light and returns through the neutral wire white.
Assuming it is a steel box.
