I can confirm the critical reviews of the previous speakers wholeheartedly; so far I have three pieces of these switches is "consumed" and all have the same problem: You can use it off no longer, because apparently the contacts are welded. Wanted The problem is every time I acted as inductive loads such. As transformers, power supplies, etc. off it. Obviously there are the switching contacts of highly inferior material which is totally inappropriate for the resulting when switching off inductive loads spark. Therefore, the things are not more than for purely resistive loads such as light bulbs and the old manufacturing company should have to write on the outside. Otherwise, it would be best waste collection would stand in front of the factory gates where the manure is produced so that you can take the garbage equal before it comes on the market, than for a switch no longer switches off if it is is not just a mistake, but may also be dangerous.
It is questionable whether all the most reviews here really relate to the same item. Although I have not bought my copies on Amazon, but they look exactly like the picture.
ADDENDUM: In the meantime I have tried using the switches around a little while the welded contacts have apparently solved again, now can be but nothing more and turn the switch no longer shine ... According sticker is the way to brand products BLANK, Model GZBK01 / 01, WEEE Reg. DE76956435, suitable for max. 16A at 230V, which corresponds, according to Ohm's law 3680Watt. More than approximately 50W so I never tried to turn and more than at most a few hundred switching operations per switch, there are not have been.
