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. Where 0 represents the off condition and 1 represents the on condition.

2 way and intermediate switch wiring diagram. Intermediate switches can be used for 1 and 2 way switching. As a part of the am2 exam you will have to wire up a 2 way and intermediate lighting circuit with one light. If replacing an existing switch note the location of the terminals and the colour and position of cable connections. This page shows it wired in the old cable colours if your house has the new colours you want to go here. It is used when you have three or more switches controlling one light the middle switch needs to be an intermediate light. This method is commonly used now days as it is efficient than the two wire control system.
3 way light switching new cable colours 3 way light switch old cable colours 3 way light switch using a two wire control. See tables 31416a b. In an intermediate switch there are four terminals by which it changes the flowing of electric current from one circuit to another see fig 1 2 and also known as three way switchit has the ability to on and off the electric supply by two ways. In a previous video i showed how a two way. This allows a single light to be turned on or off from any of the switches. There is more than one way to do this depending of the type of cable available and on the installation requirements.
The diagram shows the common method of wiring an intermediate switch into a two way light switch circuit. Intermediate switch an intermediate switch is a three way light switch. To wire a three way lighting circuit you will need 2 two way switches and an intermediate switch. How to connect 2 way switch wiring using three wire control. So now that you have a basic concept of wiring a 2 way switch lets look at the following 2 way switch diagrams to see which type of circuit scenario you have. This is the new method to make a 2 way switching connection as it is slightly different from the two wire control method.
Two cubic inches are required by the national electrical code for each 14 wire. Otherwise continue with the am2 exam guide. Here we have a 3 way switching lighting circuit sometimes called two way switching with intermediate. This video also shows how an intermediate switch works. Construction working of intermediate switch. The four terminals of intermediate switch construction and its operation are shown in fig below.
I did not include grounding conductors on the 4 way switch wiring diagrams in order to keep them simple. Follow this link if you are looking for a comprehensive step by step guide on two way and intermediate lighting circuit wiring. 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. I have a diagram for this light switch wiring method on my 3 way switch page.
