2 Way Light Switch Circuit Diagram

A selection of two way switch lighting circuit diagrams for single and multiple lights with easy to follow circuit guides.

2 way light switch circuit diagram. Whether it is the switching of a light from two different places inside a domestic dwelling or switching a series of lights in a commercial environment two way lighting circuits provide a cost effective and easy solution. If you are going to install a new one then go for three wire control method. Two way switching is the most common requirement for many household and commercial lighting solutions. 2 way light switch 3 wire system new harmonised cable colours 2 way switch 3 wire system old cable colours 2 way switch two wire control three way switching.

The first reason this is bad is on safety grounds. 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. Say we are working on the light upstairs so we turn off the upstairs lighting circuit thinking we are safe wrong the live is picked up downstairs and there are still live conductors feeding the switch upstairs and if someone flipped the downstairs switch in this diagram that live feed would extend all the way to the lamp too you re fried. 3 way light switching new cable colours 3 way light switch old cable colours 3 way light switch using a two wire control.

Pin1 pin2 of the first. This is the first method to make a 2 way switching connection this is the old method. 2 way light switch with power feed via switch two lights tags. As you see in the schematic diagram of 2 way switch circuit below you will find that the phase live is connected with the common of the first 2 way switch.

2 way switch 3 wire. This should give you a good basic understanding how the 2 way switch circuit works and will help you in adding or changing a 2 way switch. So now that you have a basic concept of wiring a 2 way switch let s look at the following 2 way switch diagrams to see which type of circuit scenario you have.
