Dimmer Switch 2 Way?

[Harden Long]

Hi

In my dining room (which has a door at either ends), there is a dimmer switch at one door(door 1 lets call it) which works fine and switches the overhead light on and off and dims it.

At the other door(door two) there is a light switch which appears to serve no useful function-I would have thought it would operate the light on and off as well. A mate who is more savvy than me reckons that the previous owners changed a 2 way switch at door one for a dimmer switch and that is why door two switch doesn't work

So, is there a way I can get door two switch to re-operate without removing the dimmer at door one or do I have to change door one dimmer for a straightforward two way???

Thanks

How many wires are behind the dimmer switch? What colours? It is possible to use a bog standard 2 way switch with a 2 way dimmer switch, normally 2 way dimmer switches are the push on/off type.

Hi Spark123 and thanks


There are 4 wires behind the dimmer switch-2 red which go into the top of the switch together and 2 yellow which go into the bottom together.

This same configuration also applies to the on/off switch at "door two"

No blue wire?

No blue wire

It could be that the wires are there so you can wire it two way however you'll need to trace where the wires go. I thought there may have been a 3c&e strapper cable which would have had a blue core as well. Is your mate a sparky?

Thanks again

My mate is not a qualified sparky although has a very in depth knowledge of electrics

I am possibly going to need a qualified spark for a couple of other jobs so will ask him to have a look at it-I had just hoped it would be a simple enough DIY job !
