A one way light switch is quite easy to wire up.
There are several ways to wire two way switching.
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 way i show allows you to fairly easily add a second two way switch to an existing light switch by simply wiring them together in a certain way.
The cable going to the light switch is connected as follows fig 2.
Below is the way i like to do it.
In this diagram two 3 way switches control a wall receptacle outlet that may be used to control a lamp from two entrances to a room.

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.
One way lighting circuit using in line switching.
The power source comes from the fixture and then connects to the power terminal.
This circuit is wired the same way as the 3 way lights at this link.
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 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.
With a pair of 3 way switches either can make or break the connection that completes the circuit to the light.
Wiring a 3 way light switch is certainly more complicated than that of the more common single pole switch but you can figure it out if you follow our 3 way switch wiring diagram.
