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 typical example of this is on a landing in a house, when perhaps there is a switch at the bottom of the stairs, one at the top of the stairs and one at the end of the landing. On this circuit you would need the middle switch (eg the one at the top of the stairs) to be an intermediate switch.
This can be continued for multiple switches, so it applies to three or more switches. Think of a shared landing in a block of flats for example.

An intermediate switch is only used on certain occasions so first of all let’s cover the other switches and when you’ll need them.
What is a normal switch?
There are two types of ‘normal switches’ a one way and a two way switch.
The Hierarchy of Switches
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).
A two way switch can be used as a one way switch or a two way switch. They are often used as both. In fact many electrical retailers (including Socket Store) don’t sell one way switches as the price difference is insignificant and the two way will do the job for both.
Why So Much More?
A final question we often get asked. Why does it cost so much more? Well the answer’s simple. It is a more complicated circuit (see the illustrations above) and therefore costs more to manufacture.
