Lights flickering

[langum25]

Hi,
Just been to a relatives flat and when I switch on the bathroom light it flickers but when I then switch on her bedroom light both lights flicker, this also happens with the kitchen light.

I can also see a faint spark coming from the bathroom light switch.

I've switched off her lighting circuit breaker as she wont be there over night. I also unscrewed the light switch for the bathroom but I couldn't see any loose connections.

Could this just be the light switch thats done or is there anything else it could be?

The helps greatly appreciated!!!

Thanks

Probably a loose connection somewhere.

Trying looking in other switches/roses.

You shouldn't be able to see sparks coming from a light switch so replace that.
Do any other lamps flickering? Do table lamps flicker? It might be more obvious using normal lamps as opposed to energy saving.

I only checked the three she had told me about. I didn't have any tools otherwise i would've had a better look. I'll replace the switch tomorrow hopefully its only that. I'll reply back once i've done it.

Thanks guys!
