Dimmer switches

MUMMYTO2BOYS

What's the difference between one way and two way dimmer switches? I've got a white one I'd like to replace with a brass one and didn't realise there were options, thought a dimmer switch was a dimmer switch. Am I being dim, is it something really obvious?

TIA :beer:

Simply, a one way is for just a single light operated by a single switch.

a two way is for when there are two switches to operate one light, like top and bottom of a staircase.

Thanks for enlightening me!

Also while I'm asking stupid questions,

TV socket Single
TV socket Isolated Single

What's the difference? What's it isolated from?

Isolated ones are required for a shared aerial, prevent your TV interfering with (or passing an electric fault back) to others on the same system.

Not really needed in a home, but not a bad thing. Only downside is they cost more and you lose a bit of the signal strength.

If other TV's in the house are running off the same aerial then a good idea.
