Could someone please explain to me,
from New Zealand, what a 4 Way switch is?.
We have over here the standard 1 way switch,
the 2way switch and the 2way+Intermediate.
What is this? [Linked Image]

Trumpy,

A 4 way has 4 terminals and goes between 2 3 ways to add another switching location:

Bill,
Thanks for your very prompt reply, all of about 10 minutes, are you staying up late?.
The diagram, that you have tendered, to me, is the same as a 2-way+Intermediate circuit,
the Intermediate, being in the middle of the
circuit.
But Bill, would the circuit be run like this in practice?.
Over here, we have a different way of running the whole circuit, all of the feed, switch and "strap" wires, terminate in the same flushbox,this is called the "Start"end of the circuit
All you have between the Intermediate and the "End" flushbox, is the same as what you have at the "Start" flushbox.
With respect to these types of lighting circuits, is there a standard colour-code for the "straps"?.

Trumpy,

No, it would not really run like this. Maybe someone else can point to a diagram that is more representative of how the wiring would run. The Neutral would run with the travelers from switch to switch and then to the load. Maybe we can get Scott to fix these diagrams so that they show that.

Bill,

I'll see what can be done this weekend. (regarding actual cabling scenarios).

Scott s.e.t.

P.S. might inbed on schematics something that kind of copywrites it to ECN (per the thread about "Mr Eelctrician").

Trumpy,
This is where most Brits would start getting confused with American terminology.

In the U.K. a 4-way switch is also known as an "intermediate" switch, and an American 3-way switch is called a 2-way. Oz and NZ obviously followed British terminology!

Compare with:
UK ground floor = US first floor
UK first floor = US second floor

FYI:

I have added circuit referenced drawings to the drawings located in the Technical Reference section, under the topic of:

3-way and 4-way Switchloop Schematics

Let me know what you think!!!

P.S. I need to alter the size of them (Way TOOOO BIGGGGG!!!). I will do this ASAP.

Pauluk,

Gee, that's funny, I thought Americans called the 3 way switch because it came from England. I read some where that over there the switch was originaly called a "3 point" switch. That being because it had 3 screw terminals. And the 4-way switch was a "4 point" switch because it had 4 terminals. When I tell people over here that a "3 way" switch operates lights from 2 different spots, and a "4 way" switch operates from 3 or more spots, they look at me like I was nuts. I believe I read this article in an American trade magazine about 2-3 years ago. Ever hear of this?

3-ways could also be named as not to confuse with single pole double throw, and 4-way not to confuse with double pole double throw.
