Electrical Wiring 2 Way Light Switch

Take the white wire leading to the second box and mark its end black too.

Electrical wiring 2 way light switch.

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. By wiring a 2 way switch the circuit below shows the basic concept of electricity flow to the load. This circuit is wired with a 2 wire cable running from the light to the switch location. 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. A 2 way switch wiring diagram with power feed from the switch light. With this done you can now start to wire the two way electrical switch to the box. First of all we should connect the ground wires to the box.

The power source comes from the fixture and then connects to the power terminal. 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. It is a standard single pole switch with three terminals.

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. The two way switch will have corresponding wires or screws. 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. If the light switch has a ground screw on it usually green and at the bottom of the switch connect it now.

Assuming it is a steel box. 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. 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.

Therefore the 2 switches the light 3 way. How to wire 2 way light switch in this video we explain how two way switching works to connect a light fitting which is controlled with two light switches. This is a completed circuit. 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.
