The choice of the specific ABB basic 55 series was made solely for the sound that the switches make when opening and closing them, which is very annoying during nighttime hours in your effort not to wake others up. Compared to the previous socket switches I had from the Legrand Valena series, they are cheaper and, most importantly, a little noisier. They still make noise, but to completely avoid it, you have to go for more expensive options.

Otherwise, if you don't care about the sound when opening and closing them, they work perfectly fine and simply do what they are programmed to do.
