An intermediate switch can however be implemented by adding appropriate external wiring to an ordinary six terminal dpdt switch or by using a separate dpdt relay. The four terminals of intermediate switch construction and its operation are shown in fig below.

Two way and intermediate switch wiring. This is the new method to make a 2 way switching connection as it is slightly different from the two wire control method. Follow this link if you are looking for a comprehensive step by step guide on two way and intermediate lighting circuit wiring. To wire a three way lighting circuit you will need 2 two way switches and an intermediate switch. An application of above using multiple switching positions to switch multiple lamps. Otherwise continue with the am2 exam guide. 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.
It should be fitted between the first and the last switches on the circuit. As a part of the am2 exam you will have to wire up a 2 way and intermediate lighting circuit with one light. This video also shows how an intermediate switch works. The addition of an intermediate cross over switch allows a two way switched lamp to be controlled from a third position. An intermediate switch is used if more than two switches are required to control a two way lighting circuit. By connecting one or more 4 way intermediate switches in line with 3 way switches at either end the load can be controlled from three or more locations.
This page shows it wired in the old cable colours if your house has the new colours you want to go here. This method is commonly used now days as it is efficient than the two wire control system. Go to my switch terminology page where i discuss the terms used for the different types of home electrical switches. Here we have a 3 way switching lighting circuit sometimes called two way switching with intermediate. First of all we need to go over a little terminology so you know exactly what is being discussed. If replacing an existing switch note the location of the terminals and the colour and position of cable connections.
In fact any number of intermediate switches can be added to add as many extra switching positions as required. There is more than one way to do this depending of the type of cable available and on the installation requirements. Wiring a 2 way switch is about as simple as it gets when it comes to basic house wiring. This allows a single light to be turned on or off from any of the switches. In a previous video i showed how a two way. Where 0 represents the off condition and 1 represents the on condition.
