REV 0509080555 Supply line switch, 3-stage dimmer switch, 20-500W, 230VAC, black

Great product but read the wiring instructions before connecting the cable , product gets warm but this is correct. Dose what it said,connected to 2 different lamps with different wattage and able to dim both to the same lux of light

Flimsy. Had to purchase a more expensive one in the end as this all broke apart on fixing up.

It's very fiddly to wire and there's almost no room between the cable clamp and the connections on the inside, and the damn thing buzzes. I can't return it as the screws are quite soft and I managed to damage them while doing them up tightly enough to hold the cable in place but if I could I would. The buzzing is loud and very irritating. Apparently this is likely to be a design flaw, according to an electrical engineer friend, rather than me just getting a dodgy one. I might have been unlucky, but you won't know until you've connected it. We've got a different make of switch on an identical lamp in our bedroom and that is totally silent, so I know silent ones are out there. Sadly we can't buy a pair for that one as it's twenty years old now!

badly manufactured
