Re: Din Rail mounted 240V AC to 12/9/5V Transformers?

[YAP <x112358@xxxxxxxxx>]

A LED, a diode reverese over the LED and a resistor (20K or so) would
be
enough for this functionality. Two or more resistors adding upp to the R
value is even better.  Of course a 'circuit' like this should be regarded
as
live (and dangerous).
