Discuss Fitting a double dimmer switch in the Lighting Forum area at ElectriciansForums.net
Thanks for your reply. I was thinking of linking up the live with the ~ and connecting with a bridging wire to the corresponding ~ on the next switch.a pic. would help. usually the permanent L goes into C or the terminal marked ~. linked to 2nd switch same terminal. then each black (switched L) into L1 of each switch.
Post a photo of how the old switch was wired. You did take one, before removing it, I trust?Thanks for your reply. I was thinking of linking up the live with the ~ and connecting with a bridging wire to the corresponding ~ on the next switch.
Then as you say connecting the blacks wire to the L1 connections. Does this mean that I do not use the other red cable which is not live.
The old switch which was fitted, probably 45 years ago was a triple rocker switch but only two working and there were two bridging wire between
some of the terminals.
Further to my reply just sent. Does the spare red connect to the ~terminal on the second switch?a pic. would help. usually the permanent L goes into C or the terminal marked ~. linked to 2nd switch same terminal. then each black (switched L) into L1 of each switch.
Sorry I took one but it is not too goodPost a photo of how the old switch was wired. You did take one, before removing it, I trust?
Put it up it may be better than nothing.Sorry I took one but it is not too good
I thought the ~ wavy line symbol was the output of the dimmer (ie feed to the lamp) so may not be good to connect permanent L to it.I was thinking of linking up the live with the ~ and connecting with a bridging wire to the corresponding ~ on the next switch.
I think the middle common does have a wire in it now I look again as per @Avo Mk8, a pic I didn't see initially but I would say is correct.
My suggestion is - whichever switch is the one you no longer need, or doesn't do anything, remove that feed to the lamp from the old switch and insulate the end of the wire with a Wago or similar, That's not to be used any more.
Then for your two dimmer switches, connect the live feed presently linking the switches to L1 on each dimmer.
Then connect the dimmer tilda ~ terminals to the remaining two lamp feeds.
Sort of like this (not my art!) - blue and yel representing the two lamp feeds, stating the obvious!

Sorry, Had an urgent call from a neighbour. I have wired the switch a different way from your o. Something is wrong as only one light is working.Did you mean to post a message Jimbob950?

I will use your method an see if that works.Hello, Thanks for your suggestion.

You've drawn 'COM' on the diagram. Is that what is actually marked on the dimmers?
Do you have a leaflet with the dimmer showing how it is to be wired?
Does the leaflet show the bulb connects to C, or the line mains power connects to C?Hello, It's marked C on the dimmer leaflet.
I think you need to verify you have the correct two wires. Mark the supply wire so you don't mix it up and connect all three wires together, if both lights work you have the correct wires.
