Water in bathroom pull switch.

[assuhors]

My daughter lives in a flat and my grandson let the bath overflow causing water to go into the flat belows bathroom pull switch.
I went round to take a look for the elderly gentleman in the flat below and when you pull the switch on the circular LED light fitting it comes on but when you turn it off the light keeps flashing. I removed the pull switch which was full of water, dried it out and put a hair dryer on it.
Now when you pull the switch on it trips the trip switch which it didn't do when it was full of water! There is a pair of wires twisted together and a single wire in the pull switch, if I choc bloc them together it puts the trip out. I can't work out why this is happening.

Water in the light aswell?

Light fitting dry. What I can't understand is why it puts the trip out now the waters dried out and not before.

Has to be a fault elsewhere, any pics of the pull cord and the wires you're putting together?

Change pull switch , could easily still contain moisture .

I think he said he by-passed it

‘’I choc bloc them together it puts the trip out’’ Wasn’t sure how to translate that .

Yes, bit confusing

I can get a picture tomorrow but basically there are two wires in the pull switch a single wire and a pair twisted together common and L1. If I join the wires together simulating the switch being pulled on it trips. It didn't trip when it was full of water just went from either the LED light being properly on or the LED light pulsing with the pull switch in the off position. I get that in the off position the water would form enough of a circuit to light a LED .

Water somewhere ,a joint or the light, are you sure it’s dry

Two wires in switch , one plus two twisted together ? Is that not 3 wires?

 

[pete01]

A single wire and a pair twisted together he also said.

looks like there`s three conductors (wires?) i think we got to seperate them and "test " what they are before going further.
