Four or more switches. The electrical switch box that contains the line and load wires may need to be bigger than the other switch boxes especially if there are other wires going into the switch box.

2 way intermediate switch diagram. The circuit consists of a two way switch at each end top and bottom switches in fig 2 and an intermediate switch in the middle. Below is another method for wiring 4 way 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. Follow this link if you are looking for a comprehensive step by step guide on two way and intermediate lighting circuit wiring. All three switches are connected together by a three core and earth control cable. Otherwise continue with the am2 exam guide.
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. The middle switch is an intermediate type. More 4 way switch wiring diagrams four way switch wiring schematic. There is more than one way to do this depending of the type of cable available and on the installation requirements. Two wires between each switch. Alternative method of three way switching.
Most likely to be found with wires in conduit. This is an alternative deprecated form see above for the reasons of the multi way switch wiring. If you are going to install a new one then go for three wire control method. This is a very versatile switch and can be used for most lighting situations but in reality it is more expensive so you would normally only use it when needed. Two way switch diagram. And so onto the intermediate switch.
All of the additional switches are internediate types 4 terminals and connect into the middle of the. That is when you have three switches controlling one light then the middle one needs to be an. The switches at each end are 1 pole 2 way switches. 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. Notice that the wire connected to the com terminals is looped straight through the intermediate switch using a cable connector. Any number of intermediate crossover switches may be added to give three or more switching positions.
What does a 3. Pin1 pin2 of the first. This is the first method to make a 2 way switching connection this is the old method. An intermediate switch is a three way light switch it is used when you have three or more switches controlling one light the middle switch needs to be an intermediate light switch. The switches at each end are 1 pole 2 way switches. Both of the three way switching diagrams can be extended to four five or even more switches.
As a part of the am2 exam you will have to wire up a 2 way and intermediate lighting circuit with one light. The four terminals of intermediate switch construction and its operation are shown in fig below. As you see in the schematic diagram of 2 way switch circuit below you will find that the phaselive is connected with the common of the first 2 way switch. Construction working of intermediate switch.
