The four terminals of intermediate switch construction and its operation are shown in fig below. 2 way switching means having two or more switches in different locations to control one lampthey are wired so that operation of either switch will control the light.
2 Way Switch How To Control A Lamp Two Or Three Locations
Two way intermediate lighting wiring diagram. Otherwise continue with the am2 exam guide. To wire a three way lighting circuit you will need 2 two way switches and an intermediate switch. These diagrams show various methods of one two and multiple way switching. Follow this link if you are looking for a comprehensive step by step guide on two way and intermediate lighting circuit wiring. Construction working of intermediate switch. 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 way switching is the most common requirement for many household and commercial lighting solutions. Line diagram of a two way lighting circuit using junction boxes fig 1. This allows a single light to be turned on or off from any of the switchesthis page shows it wired in the new cable colours if your house has the old colours you want to go here. Two way switching 2 wires. Three way switching old cable colours. This arrangement is often found in stairways with one switch upstairs and one switch downstairs or in long hallways with a switch at either end.
This video also shows how an intermediate switch works. By wiring a 2 way switch the circuit below shows the basic concept of electricity flow to the load. Switches are shown as dotted rectangles. In a previous video i showed how a two way. Here we have a 3 way switching lighting circuit sometimes called two way switching with intermediate. L and n indicate the supply.
The junction box should be wired as shown below. There is more than one way to do this depending of the type of cable available and on the installation requirements. Lets assume the load you are controlling is a light. As a part of the am2 exam you will have to wire up a 2 way and intermediate lighting circuit with one light. The electricity flows from the hot wire black through the 2 way switch shown in off position and then to the light and returns through the neutral wire white. Video explains the connection required within two way and intermediate switches.
Whether it is the switching of a light from two different places inside a domestic dwelling or switching a series of lights in a commercial environment two way lighting circuits provide a cost effective and easy solution. Student training aid for the connections required to wire two way and two way and intermediate switching. Explanation of above picture. Earth wires are not shown. The most basic circuit with only two wires at the switch. Two way lighting circuit using three core earth cable.
