2 way and intermediate switch wiring. Construction working of intermediate switch. Where 0 represents the off condition and 1 represents the on condition. 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. If replacing an existing switch note the location of the terminals and the colour and position of cable connections. Intermediate switches can be used for 1 and 2 way switching. This method is commonly used now days as it is efficient than the two wire control system.
This is the new method to make a 2 way switching connection as it is slightly different from the two wire control method. A two way switch can also be wired in such a way that it can be used as a one way switch mostly the price difference is negligible. Follow this link if you are looking for a comprehensive step by step guide on two way and intermediate lighting circuit wiring. The four terminals of intermediate switch construction and its operation are shown in fig below. How to connect 2 way switch wiring using three wire control. Here we have a 3 way switching lighting circuit sometimes called two way switching with intermediate.
As a part of the am2 exam you will have to wire up a 2 way and intermediate lighting circuit with one light. This allows a single light to be turned on or off from any of the switches. This page shows it wired in the old cable colours if your house has the new colours you want to go here.
