Replacement Bathroom light/extractor fan.

Our Kingham Bathroom light/extractor fan has a failed switch. The original part is now obsolete, has anyone replaced theirs with a new model that they could recommend?
Thank you.

I have a similar switch in mine but its working....just...
I would be interested in a better switch too.

What does the switch look like? Ours is a round black one available on eBay.

It’s this one, the switch is on the side of the light[You must be registered and logged in to see this link.]

Same switch on Lumo Crown (the round version). We also have the coronet  on ours, switches are very hit and miss. Lumo have ceased trading. I'm sure there must be a switch you could replace it with.
