What is the difference between 1-way, 2-way, and intermediate switches?

How to choose the right light switch – a quick guide from the pros
Choosing the right light switch isn't always as simple as you might think.

Should it be 1-way, 2-way, intermediate, or perhaps double 2-way?

Here, we explain the differences and help you choose the right one – whether you're an installer, a DIY enthusiast, or a property owner.

 1-way – the classic light switch
The most common switch.
Used to turn a light source on/off from one location.
 Perfect for bedrooms, kitchens, bathrooms, and storage rooms.

 2-way – control from two locations
Do you want to be able to turn lights on and off from two locations?

Then a 2-way switch is what you need.
 Common in stairwells, hallways, and bedrooms with two doors.

 Tip: Combine two 2-way switches – one at each end of the room.

 Intermediate – two lights, one location
An intermediate switch has two buttons and controls two different light sources.
Example: One button for a ceiling lamp, one for wall lighting.
 Common in living rooms, kitchens, or conservatories.

 Double 2-way – looks like an intermediate switch, but controls from two locations
Similar to an intermediate switch in appearance – but used like two 2-way switches.
 Can control two lights from two different locations.
