strange

Decided to put some new downlights in the alcove yesterday..small chase in the wall for my new switch wire so I could switch them seperate to my main living room light..located some jbs under the floorboard.. Switched all downstairs lights off and found what I thought was the mains..wired my lights\switch into the jb..turned the breaker on lights look well..

Mrs turns on the dining room light my downlights in the living room go out ha ha

Opened up the jb and found what I thought was. Mains cable was in fact the dining room switch wire that shows 240 when the switch is off and 0 volts when the light is on..

Hmmmm going to take a look at the connections above the dining room light when back in from work..

Not really strange, that's what will happen if you connect to the wrong cable !

You will probably find your downlights are also dimmer than they would be, and that when they are on, the dining room light glows dimly...

Ok smartarse
Strange that I'm getting 240 when the light is off hence why I connected to the wrong cable

The lamps are cool white 4watt leds so didn't notice anything dim about them..no mate there was no issue with the dining room light.. I pretty much disconnected the switch wire straight away as I obv realised I can't use that cable..I need to see what's connected elsewhere to find the cause of the voltage readings I'm getting when the dining room light is off

There's nothing wrong with the readings you got!

There is no neutral in your switch, just alive and sw live.

240v live to sw live when off (as lamp in place)
0v live to sw live when on, as both sides are at 240v, so 0v between them.
