3 way lighting

[davecooper]

Thanks Riveralt. That has told me all I need to know.

He told you that in the very first reply....

I was replying to his first post. My second post was only added to highlight (in my view) how descriptions of switches can be misleading. Mine are marked as 2 way on the packaging when they are actually single way 2 pole. Anyway, happy now.

An intermediate switch is a switch that sits between 2 2way switches. The intermediate switch doesn't carry a common which is why in a domestic setting you will see the common terminated into a connector block or similar. It only carries the 2 strappers (in/out) if you have a problem try and find a diagram explaining the conversion method of a 2 way switch and understand that first. Don't be confused with the conventional method which is only really used in conduit wiring systems as you run the separate cores individually.

2 pole switches have 4 connections, they are usually used where double poled isolation is required i.e. where you want to break line and neutral.

2 way switches have 3 connections, one common and the other two connections connect to the common (one or the other) depending on the position of the switch.

Intermediate switchs have 4 connections, 2 in and 2 out. Depending on the position of the switch they either connect straight through or cross over.

A 1 gang switch is a single switch on a plate, it can be 1 way, 2 way, intermediate, double pole etc etc etc.

A 2 gang switch has two switches, unless grid are two of the same type.

Mine are marked as 2 way on the packaging when they are actually single way 2 pole.

Then they were wrongly described and you could (should? did?) get them replaced.

Descriptions can't be misleading unless they are wrong - it's not a question of interpretation, or different conventions - a single pole 2-way switch is not the same as a 2-pole 1-way.
