Hi guys, this 3 way switch controls the main bathroom light, a second light and the extractor fan. Been flashing occasionally when turned on, so seems it needs a new switch. Anything to watch for here or is it just a case of getting a new switch and copying the wire/terminal layout ? (And remembering what went where).
New light switch

3 gang - 3 way would be 3 switches at different positions operating one light.
Could just be a loose wire.
Yes mark the cables before removing and take a picture.
Remember the switches are just three separate switches next to each other with no connections between them.
It will be just a straight swap but one of the switches might be inverted and the terminal markings might be different.
Thank you. Could you just elaborate on the above a little please?
All switches the same way around...
One of the switches inverted (for better utilisation of space)...
These images also show some differences in the labelling.

I came across one recently, can't remember the exact order but laid out something like this
With no indication which was 'COM'. I was replacing a 3G all used as 2way with just 3x 3C&E
Which was COM?
That could be the lamp itself, I have you tried another one? Or, the lampholder.
If it's the switch, usually tapping the switch, will provoke the flashing - likewise the lampholder.
A
But of course I assumed C
Thanks. Little confused about the bottom setup there. Would this be the correct grouping for one way X 3?
Yes, I'm aware of com and L1 matchups but on that switch it's not clear which is the com for the first gang. That's why I asked if my markings were correct?
Yes, your markings are correct.

Yeah, it's odd.
I know what you mean but for us oldies who were accustomed to the old ceramic switches with screw-on covers where the entirety of the brass and copper contents were on view.
In essence there would be 2 fixed contacts and a moving contact. In one position the top contacts are linked and in the other the bottom contacts are linked.
Some had 2 distinct switches.
That's converted to a 2 way switch by either adding a wire link and some makers installed a bar to link 2 terminals together. Some of those had a dummy terminal (blank rivet).
I'm sure that makes plenty of sense.
Some had the link bar and an actual 4th terminal which was handy for the loop out.
