That sounds like the answer. The intermediate switch by one side of the bed and the 2-way switch by the door were easy to replace as they matched the new switches. The 2-way on the other side of the bed was a really old light switch which didn’t have Com marked. I assumed that L1 on the old...

I replaced three light switches in our bedroom, two are 2-way and one is an intermediate switch. I carefully followed the existing wiring, but now one of the 2-way switches if it’s switched on makes the other two switches not work. If it’s switched off then the other two switches work as...

Ahh but without your kind help I’d be sitting in the dark with a grumpy wife, so I am very grateful!

Rather stupidly I didn’t take any photos as I’d already done the other light switches in the house by just copying the connections to the new light switch. I’ve tried connecting wires to both of the com wires (in the original switch they were twisted together and only in one of the com...

I hope that someone can help with a light switch problem. There is a single light switch which controls the lounge lights and it’s wired like this: C6990933-7979-4260-AEBF-C94C165FB7D8 by RogPJ posted 14 Feb 2021 at 12:40 PM Then there is a double light switch which also controls the lounge...
