2 separate lighting circuits on the same switch..allowed???

[dtec dave]

Following my last post I decided to keep all my outdoor lighting on thier own separate circuit, so my next problem is how to switch them. My initial idea was to have a 3 gang switch and use 2 of the ways for internal and 1 way for the security light, but I was thinking if someone isolates the internal lighting to remove the switch the external part will be still live. Is this acceptable or do I need my own separate 1 gang switch for the outside lighting and a 2 gang switch next to it for the internal.
I didn't realise something this simple would give me such a headache!! Roll on a bit of experience.

Cheers

You can do it. Put a label inside the switch warning that there are 2 supplies at the switch

Having all 3 lights at the same switch is Ok. It no different to 2 way switching of up and downstairs really.

Do you have the neutral at the switch?

 

[dtec dave]

ok..I suppose you have a similar senario when you switch an upstairs circuit from downstairs.

No don't have a neutral, they are at the light fitting end. I was just concerned about having different circuits at same switch.
