One of the few (obviously!) things I remember from physics at school

that you should use the appliance switch if it has one to avoid
damage,
rather than the socket switch or pull the plug. Is there any truth to
this?

Rob

It depends. If the appliance switch is simply turning off the incoming
mains (the traditional way to do it), then pulling the plug or
switching off at the socket is exactly equivalent. If the appliance
switch works through some electronic function, then it isn't.

But whatever the case, there should be absolutely no danger of damage.

You never seen a wall socket with one hole a bit bigger than the other,
with
blackened edges....???



Errrrmmmm..... No.



Errrrmmmm..... Really?

I have on a number of occasions.

How about seeing a flash when pulling a plug out? (Like even through the
white plastic?)


Maybe when unplugging something really meaty - but never anything like
a Hi Fi.


I did a projector swap the other evening using the same kettle lead that was
already plugged in and got a little 'plip' as I plugged the thin end into
the PJ - thus, I suspect, nearly reducing myself to *two* frazzled PJs at a
stroke!! I have no idea how many times I've heard fizzing/pops/cracks
pulling plugs out (audio gear) over the years - usually because I was in an
awkward position and not able to do it quickly and cleanly....
