Noting that I've located the Wiki and am working my way through it,

I did want to check one thing.

It says that with a neon indicator on a light switch (find in the dark) it
is wired between live and switched live and so is only lit when the switch
is off.

I assume that this means that with current taking the path of least
resistance, when the switch is on the current flows through the lighting
circuit and not through the higher resistance of the neon.

All well and good until I consider an application where the neon comes on
when the circuit is live. I assume there is a different resistance in the
neon to allow it to light in parallel with the main circuit.

Is this correct?

A light that comes on when the switch is on requires a neutral wire, and
is wired between neutral and switched live. Not a problem in your
appliance, but can be a nuisance to supply at a light switch.
