The hierarchy of switches. That is when you have three switches controlling one light then the middle one needs to be an intermediate switch the others need to be two way.
Intermediate Light Switch Wiring Light Wiring
Two way lighting circuit with intermediate switch. 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. This is also known as the conversion method since it is the easiest way to add a second light switch to an existing circuit. The four terminals of intermediate switch construction and its operation are shown in fig below. Three wires between the two end switches probably using 3 core and earth cable. Usually the third wire passes the middle intermediate switch but is joined in a separate terminal block.
Follow this link if you are looking for a comprehensive step by step guide on two way and intermediate lighting circuit wiring. A two way switch and an intermediate switch. This page shows it wired in the old cable colours if your house has the new colours you want to go here. Intermediate switch diagram. This allows a single light to be turned on or off from any of the switches. Video explains the connection required within switches.
There is more than one way to do this depending of the type of cable available and on the installation requirements. Otherwise continue with the am2 exam guide. Again the names of the type of switches depends where in the world you live. Three way switching 3 wires. Here we have a 3 way switching lighting circuit sometimes called two way switching with intermediate. Construction working of intermediate switch.
However the two way has 3 terminals on the back. The two way and intermediate switch will look the same on the front. 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. The circuit is wired in twin and cpc cables twin and earth cable and 3. To make this circuit work we require two different types of switches. Also how to wire two way and two way and intermediate switching.
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. 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. 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. An intermediate switch can be used as a one way or two way switch but is more expensive so would not normally be used for this.
