Inteterseting - as I have had a LOT of failaure of MK dimmers - they
still
work as switches but fail to dim.


Yes. Had this with non MK dimmers. Candle bulbs arc over when they go
and rip the triac guts apart. Replace with bigger triac.

MK don't do electronics I think - the dimmer modules are probably bought
in by them from elsewhere.

In reality you need a 20A plus triac to control e.g. a 2A load So the
MCB trip goes before the triac, not the oher way about.

Who makes the 20A triac units?
