My cooker switch is wired in a way that the neon indicator is always
on, whether the switch is on or off. Is this correct? (I am under the
impression that the indicator should be in sync with the switch). The
cooker is mixed-energy: gas hob and electric oven, if that matters.
Moreover, I have two wall light switches that also have neon
indicators and the indicators are always on regardless whether the
switches are on or off. They must be wired by the same electrician.
But is this correct?
Sounds like the input and output from the switch are reversed. Not a safety
issue, but annoying.
If they are there to 'see' the switch in the dark, it's normal to have them
on with the light off, and off with it on. If it's a normal lighting
circuit, it sounds like he might have wired one side to earth, given that
there's not normally a neutral at a switch.

With incandescents, there's no need to wire the cold end of the neon
to earth: the neon goes across the switch contacts, and the cold resistance
of the blub forms an effective path to neutral (being massively lower than
the 'internal resistance' of a neon indicator). With the switch on, there's
no potential across the neon, so it goes out. A downside of this Ingeneous
scheme is that if the bulb blows, the indicator no longer lights; and it's
shot to pot if you use compact-flourescent or similar.
As for the cooker switch, it sounds as you say very much as if the wiring
to the 'Feed' and 'Load' sides of the switch have been swapped round.

Funnily enough, we have one circuit with two compact fluorescents on it
(nearly the same, apart from the white powder! :-)). It has one of
these neon visibility things on the switch and it still seems to work OK
(there are no incandescents in the circuit).
Don't know WHY, mind....!

A large R across the fluorexcrescent?
That would be enough to light the neon.
I have a neon visibility thing on a circuit connected to a HF
ballasted fitting with emergency maintained capability.
Must be an R there as well

No, it is wrong. The indicators are to indicate that the switches are
The terminals should be marked something similar to 'in' and 'out', one
for each L and N. Your 'electrician' has got the 'in' mixed up with the
