2 Gang Double Switch Problem

[littlespark]

you wont get a bang. Theres no neutrals at the switches... just don't attach any cables to the earth.

I thought the symbol with the sine wave and the arrow is for the dimmed output?
Also, I’m counting 2 of each colour at the 2 gang dimmer switch, which suggests two 3 core cables?

I suspect it’s actually 2 way 3 wire, considering there are 5 cores at the dimmer.

I would test to see which is the switch line but suspect it’s the blue currently in the left dimmer in L2.

If it was 3 wire then the red link would need to go into L1 in the dimmer - not the common, and the plate switch would be blue into L1, red into common, yellow into L2.

It’s not 5 cores, it’s six.

I count 5 in that left dimmer?

The other dimmer is just one way (I think).

no.it's the common.

Both of the connectors in the first 3 pics are dimmers. It a double dimmer switch. At the moment it works and dims both lights. So you think the two blues going in together shouldn’t be? Any idea where I should move one of them to? Sorry to be a pain.

One of the sleeved blues should go into the other switch, without looking at the back box or belling it out, it’s impossible to know which one. The rule with two way lighting is, whatever colours go into L1,L2 and Common in the main switch goes into the same one in the other, si your yellow, blue and red should be in the corresponding terminals in both switches.

Without further investigation, that’s the best I can do

Good luck

If that’s the common, then it shouldn’t be used to feed the second switch.
The live into the first switch, needs to go to either L1 or L2, with the switched live in the other L1 or L2 terminal.

I was thinking that the feed for the plate is going into the one way dimmer common first.....

Could be.
Either way it would make the 2 way common live all the time.
Live feed in needs to go to L1 or L2.
Switched live from the other L1 or L2 terminal.
Unless the switched live is at the other end, but then you wouldn’t need 3 core between the switches.

Move the blue from L1 to common.
Move the blue and yellow from L2 to L1.
Move the 2 reds from common to L2.
At the other end move the blue from L3 to L2.

Weird, I’m in middle of four lighting threads at the moment.
Two here and two on another forum.

Thank you all so much for your replies. I have been poorly for a few days so just catching up. I will try some of your suggestions. Spinlondon, your remedy sounds the most simple for my little brain I will try tomorrow if I am feeling better and report back

Quick update. I have been in hospital (no I didn’t blow myself up lol) so haven’t even looked at it, but I will do in a few days maybe, and try some of your suggestions, and report back. Thank you all for taking time to reply, it is much appreciated
