Bathroom fan switch

[SUNRAY]

Just thought, domestic accessories are rated at 250V so shoudn't have 400V between contacts.

Yes, I realised that was an issue that some might raise but, as I said, provided the switch was definitely (and 'reliably') break-before-make, I don't really see a problem - I'm sure that the insulating material between the two contacts/terminals, per se, would be more than able to cope with 400V between them.

Adding 2 more photos of fan and switch wiring

didn't know that rule.
But that's not an intermediate switch.

probably a wiring error at the switch.

Start by seeing what colours are present at the fan if easy.

Is that brown and red wire in the same terminal hole ? Take one out.

To me a timer fan has been replaced with a normal fan

That's the problem in the orange circle, the 'permanent live' and 'switched live' should not be connected in the block together. I'll guess the brown is permanent however I can't be certain, the damaged blue requires repair in some way.
