Individually switched extension leads

An individually switched extension lead allows connected electrical devices to be controlled separately. Instead of switching the entire extension lead on or off at once, individual sockets or socket groups can be switched according to the model.

This is particularly practical when several devices share one extension lead but do not always need to be powered at the same time. Typical applications include desks, home offices, gaming setups, entertainment systems and workspaces.

What is an individually switched extension lead?

With a conventional switched extension lead, one main switch usually controls all connected devices together. An individually switched extension lead provides additional switches for individual sockets or groups of sockets.

This means, for example, that a monitor can be switched off while a router remains powered, or a printer can remain disconnected from the mains until it is actually needed.

Depending on the model, an extension lead may also combine individually switchable sockets with a main switch, permanently powered sockets or other switching functions.

What are the advantages of individually switched sockets?

The main advantage is greater control over the devices connected to the extension lead. Equipment that is not currently required can be switched off without interrupting the power supply to other devices.

Individually switched extension leads can therefore be useful when:

  • some connected devices need continuous power while others do not
  • devices are difficult to reach behind or underneath a desk
  • several devices are used at the same workstation
  • standby consumption should be reduced where possible
  • devices should be switched independently without unplugging them

Individually switched extension leads for home offices and desks

A desk or home office often contains several electrical devices with different usage patterns. A router may need to remain powered continuously, while a monitor, printer, speakers or charging equipment may only be needed at certain times.

With individually switched sockets, these devices can be controlled separately without unplugging their mains plugs each time.

When choosing an extension lead for a desk, also consider the number and arrangement of sockets, cable length and the amount of space required by larger power adapters.

Individually switched extension leads for gaming and entertainment setups

Gaming and entertainment setups can include televisions, monitors, consoles, speakers, chargers and other equipment. Not all of these devices necessarily need to remain connected to the power supply at all times.

An individually switched extension lead makes it possible to control selected devices separately while leaving equipment that requires continuous power switched on.

For sensitive or valuable electronics, additional features such as surge protection may also be worth considering depending on the application.

What is the difference between a switched and an individually switched extension lead?

A standard switched extension lead normally uses one switch to turn all switchable sockets on or off together.

An individually switched extension lead provides separate control over individual sockets or socket groups, depending on the product design.

The individually switched version is therefore particularly useful when connected devices have different power requirements or are used at different times.

Can individually switched extension leads help save electricity?

Switching off devices that would otherwise continue to consume electricity in standby mode can help reduce unnecessary power consumption. An individually switched extension lead makes this particularly convenient because only the devices that are not required need to be disconnected from the power supply.

However, not every electrical device should necessarily be disconnected after use. Some equipment may need continuous power or perform functions while in standby. Always follow the manufacturer's instructions for the connected device.

More information on standby consumption and switching devices off is available in Save electricity with extension leads with switch.

What should I look for when choosing an individually switched extension lead?

The most suitable model depends on the devices being connected and where the extension lead will be used. Important factors include:

  • Number of sockets: Choose enough outlets for the devices you regularly need to connect.
  • Switching options: Check whether every socket can be controlled separately or whether some sockets are combined into switchable groups.
  • Socket spacing: Wider spacing can be useful for large plugs and external power supplies.
  • Cable length: The cable should reach the intended location without being stretched or creating unnecessary excess cable.
  • Maximum electrical load: The combined power consumption of all connected devices must remain within the rating specified for the extension lead.
  • Additional features: Depending on the application, surge protection, USB charging or mounting options may also be useful.

Can all sockets be used at the same time?

The number of available sockets does not determine how much electrical power can safely be drawn through an extension lead. Even if every socket is occupied, the combined electrical load of all devices operating at the same time must remain within the maximum electrical load specified for the individual product.

Several low-power devices may remain well below the permitted maximum load, while only a few high-powered appliances can use a large proportion of it.

How to calculate the combined load of connected devices is explained in our article on the maximum load of an extension lead.

When is an individually switched extension lead useful?

An individually switched extension lead is a practical choice whenever several devices share one power connection but need to be controlled independently.

It combines the convenience of a multi-socket extension lead with greater control over individual devices and can help avoid unnecessary standby consumption where equipment can safely be disconnected from the power supply.
