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