More often than not, they aren't.

I don't think so. Even in my case with a 2-pole switch they are.

But one would ideally want to isolate the live, switched live, and the neutral.

I don't understand your point. My 2-pole isolator does this - but for both the bathroom light and the fan.  A 3-pole one can do this for the fan only, without affecting the light (and its wiring will differ).

Ah, I misunderstood that you had a two-pole to isolate only the extractor (independent of the light), as that was what I was talking about in my post to which you replied.

This is basically how I do my wiring because the extractor always seems to require a SFCU:

If the double pole pull switch is a high current isolator type for showers etc., they can be harder to operate.

Another option is to use a 3-pole fan isolator with integrated fuse:

Very loud in the dead of night, too!

The spacing of the stencilling on that faceplate displeases me

Scolmore do an alternative but it doesn't look as good (Click range):

They are only double pole.  @Grenage mentions a pull cord switch in the diagram above.

Ah that looks much tidier

Ah, I see...

Are there any low-current double-pole?
