In the world of lighting and electrical systems, terms like series switch and two-way switch are sometimes confused, which often causes confusion. In this blog, we clearly explain the difference between these two circuits, when to use which, and how to wire them. This way, you will know exactly which switch suits your situation and avoid unnecessary mistakes.

Double Pole Switch
Connecting a double pole switch is not complicated, but it is important to know exactly which wires to use for a double pole switch. The double pole switch has three connection points:
- Two for the switch wires that run to the individual lamps.
- One for the live wire that supplies the power.
In a series circuit, only the switch wire is interrupted.De neutral and earth wires remain untouched and are directly connected to the light point. This allows you to operate two light sources separately with a single switch.
Always make sure to turn off the power before starting the installation. Then carefully check that the correct wires are connected according to the wiring diagram of the double pole/series switch. This prevents malfunctions and ensures the safe operation of your lighting.
How do you connect a series switch?
Connecting a series switch is not complicated, but it is important to know exactly which wires you are using. The series switch has three connection points:
- Two for the switch wires, which run to the individual lamps.
- One for the phase (live) wire, which supplies the power.
In a series connection, only the switched wire is interrupted. The neutral and earth wires remain unaffected and are connected directly to the lighting point. This allows you to control two light sources separately with a single switch.
Always ensure that you turn off the power before beginning the installation of the series switch. Afterwards, carefully check that the correct wires are connected according to the wiring diagram of the series switch. This prevents malfunctions and ensures the safe operation of your series switch.

Two-way switch
Do you want to control a single light point from two different locations? Then you need a two-way switching circuit .This type of circuit is often used in long hallways, stairwells, or larger living spaces. Think of a light that you can turn on downstairs and turn off upstairs, for example. A two-way switch is also known as a hotel switch, because this principle is frequently used in hotels, for example to control the light 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 independently switch the light on and off from two locations. Our two-way switches are available in various designs and fit virtually any switching material.
How do you connect a two-way switch?
Connecting a two-way switch requires a little more attention than a standard double switch, but is entirely manageable if you know how the wiring works. The two-way switch features three connections:
- Two for the switch wires (the input and output).
- One for the live wire, which supplies the current.
Instead of looping the live wire through to multiple lights, you use a lamp wire here that runs directly to the light point. You then connect the two switch wires to the other two-way switch so that both switches work together. The neutral and earth wires remain connected to the light point itself.
Always ensure that the power is completely switched off before you begin installation. By connecting the wires according to the diagram, you ensure a safe and reliable two-way circuit that allows you to easily operate the same light from two different locations.
