Two means lightweight shift

Here area unit step by step directions on {how to|the means to|a means to} wire up a 2 way light circuit or to vary a existing a way lightweight switch to a 2 way system, this is often terribly helpful on stairs etc. as you’ll be able to have a switch at rock bottom and also the high of the steps.

Two means shift isn’t as troublesome because it initial appears and may be pretty straight forwards if you follow the diagrams below.

Earth wires are omitted from all photo’s and diagrams for clarity, however should be connected the least bit earth terminals. Two-way lightweight switches area unit needed for 2 means shift, these will be known by gazing the terminals on the rear of the switch . there’ll be a Com (common) terminal a L1 terminal and a L2 terminal.

Two means shift with the recent wiring colours

 

This diagram represents a 2 means shift arrangement. There area unit alternative ways in which of wiring a 2 means light circuit, however this is often far and away the foremost common and easiest way. The recent wiring colors that area unit gift within the majority of homes within the United Kingdom of Great Britain and Northern Ireland are used for this diagram. 3 core and earth cable is needed to put in 2 or 3 means shift and this could be run from the primary lightweight switch to the second then wired as shown during this diagram. Switch one is that the switch that contains the busy bee and switched busy bee. The diagram shows single colors solely. In world these wires would be coated by associate outer protecting sheath and would come with a clean earth wire and would be referred to as a cable. Red sleeving or tape would of been placed on the wires as shown to {point out|to indicate} that they might be live at some point. currently this sleeving would be brown. The connections area unit terribly easy and there’s another guide additional down this page.

Two means shift with the new consonant colors-

 

This is constant diagram as on top of, however victimization the new harmonic colors. 3 core and earth cable is needed to put in 2 or 3 means shift and this could be run from the primary lightweight switch to the second then wired as shown during this diagram. Switch one is that the switch that contains the busy bee and switched busy bee. The diagram shows single colors solely. In world these wires would be coated by associate outer protecting sheath and would come with a clean earth wire and would be referred to as a cable. Brown sleeving or tape would of been placed on the wires as shown to {point out|to indicate} that they might be live at some point.

How to convert one switch to a 2 means system

 

Here you’ll be able to see the rear of a light-weight switch, during this instance it’s a 2 means switch getting used for a 1 means lightweight. a 1 means switch has solely a typical and L1 terminal and a 2 means switch contains a common, L1 and L2 terminal, like this one within the image. Note that new consonant cable is getting used (Brown and Blue) and note that Brown sleeving has been placed over the Blue wire, This signifies that it’ll be live at some point! the world wire must always be connected to the attachment terminals, it’s been removed for clarity here however should be connected, even on plastic lightweight switches, unless there’s no attachment terminal. the rear box can would like attachment unless it’s plastic and there’s no attachment purpose.

 

For two means shift you wish a length of 3 core and earth cable long enough to achieve from the present lightweight switch to the place wherever you propose putting the second lightweight switch.

This cable wants routing via the best route, here area unit the rules and permissible zones this is not the new consonant cable, therefore, the colors might have ever-changing, the world sleeving still wants victimization before association like all cable.

There are not any set rules that wire will what in 3 means lighting, however, I’m planning to use the foremost smart possibility.

 

Remove the wire that is within the common terminal and place it within the L2 terminal.

These 2 wires area unit the permanent live and switched live wires.

There are not any fastened laws that wire goes wherever however if you follow the colors that I actually have used here, they appear to create sense!

Note however all of the wires have brown sleeving on them! I actually have softened this back a touch then you’ll be able to see the particular colors of the wires. The brown wire and also the blue wire that’s sheathed  brown area unit already in terminals L1 and L2, this is often delineated  on top of. These 2 wires area unit the Permanent live and switched live.

The Yellow wire goes within the common terminal, Red within the L1 terminal and Blue goes within the L2 terminal.

The gray wire goes within the common terminal, Brown within the L1 terminal and Black goes within the L2 terminal. once ever you fasten a wire into a terminal, continuously provides it a mild pull to make sure it’s fixed properly. this could save hours of labor shortly once the wire pops out and stops working!

 

This is the rear of the second switch that may build the circuit a pair of means, another time the brown sleeving has been softened back for clarity. The wires during this switch ought to mimic precisely the 3 wires that you simply have place within the alternative switch.

The Yellow wire goes within the common terminal, Red within the L1 terminal and Blue goes within the L2 terminal.

The gray wire goes within the common terminal, Brown within the L1 terminal and Black goes within the L2 terminal. You currently have a light-weight that may be switched on or aloof from a pair of totally different locations.
