In the world of lighting and electrical engineering, terms like series switch and two-way switch are often confused with one another, which frequently leads to confusion. In this blog, we clearly explain the difference between these two circuits, when to use which, and how to connect them. This way, you will know exactly which switch fits your situation and avoid unnecessary mistakes.

Series switch
Do you want to control two light points from a single location? Then you need a series connection. This type of connection is commonly used in rooms where you want to operate multiple lamps separately, but want to use only one switch, for example in a living room with two light groups or in a bathroom with ceiling and mirror lighting.
A series switch basically consists of two switches in one housing.Each switch controls its own light point or group, allowing you to independently decide which lamp to turn on or off. This helps you keep an overview and saves space, as you don't need to install two separate switches.
Series switches are available in various types and designs, fitting almost any switch range. They are a practical and elegant solution for anyone who wants to control multiple light sources from a single location.
How do you connect a series switch?
Connecting a series switch is not difficult, but it is important to know exactly which wires you are using. The series switch has three terminals:
- Two for the switch wires leading to the individual lamps.
- One for the phase wire that supplies the power.
In a series circuit, only the switched wire is interrupted. The neutral wire and earth wire remain unchanged and are connected directly to the light fixture connection. This allows you to control two light sources separately with a single switch.
Always turn off the power, before you begin installing the series switch. Then carefully check whether the correct wires are connected according to the wiring diagram of the series switch. This way, you prevent malfunctions and ensure safe operation of your series switch.

Two-way switch
Do you want to control a light from two different locations? Then you need a two-way circuit.This type of switching is often used in long corridors, stairwells, or larger living spaces. A typical example is a lamp that you can turn on downstairs and turn off upstairs. A two-way switch is also known as a hotel switch, as this principle is often used in hotels, for example to operate the light both at the entrance of the room and next to the bed.
A two-way switch always works in combination with a second two-way switch. Together, they allow you to turn the light on and off from two independent locations. Our two-way switches are available in various designs and fit almost any switch range.
How do you connect a two-way switch?
Connecting a two-way switch requires a bit more attention than a single-pole switch, but is entirely manageable if you know how the wiring works. The two-way switch has three terminals:
- Two for the switching wires (input and output).
- One for the phase wire supplying the power.
Instead of looping the phase wire to multiple lights, you use a lamp wire here that runs directly to the fixture. You then connect the two switching wires to the other two-way switch so that both switches work together. The neutral wire and the earth wire remain directly connected to the fixture.
Always make sure that the power is completely turned off, before you start the installation. By connecting the wires according to the wiring diagram, you ensure a safe and reliable two-way circuit, allowing you to easily operate a light from two different locations.
