Replacing dimmer with rocker - wiring dilemma.

My hall is switched from 4 positions. Therefore I have 2 x "two way switches and 2 x Intermediate switches.

The OP will find that when he buys a three-gang switch that each gang will be two-way (for simplicity of manufacture / stocking)

That's poor design then, they should have limit switches so you can just flick them to up and not worry. I suppose its the elf getting in the way again.

They have limit switches - but you don't always want the screen fully unwound. Limit switches are a back-up and not intended for constant use - also using a sprung-centre switch means that most of the circuit is isolated most of the time - unless being operated. Better practice.

I do know the difference between gangs poles and ways its just if you google for 3 way lighting switching guess what you get? 2 way and intermediate circuits

Some US sites talk of 4 way as well.

I guess the terminology is almost acceptable as long as people realise it is the name of the type of circuit - and NOT the type of switch. I still think it is better to differentiate by saying - 3 LOCATION switching - or 4 LOCATION switching and leave the type of switch to someone who really knows.
