Had this switch bought to replace my none-name switch from the hardware store, because this was a continuous, relatively loud rattle of itself, which already disturbed in the long run. Maybe I should mention that I so that the light of my Nano Aquariums control what is on my desk. Well, as I pocketed the Vivanco clock, was only once completely silence ........... very pleasant. However, after about 3 weeks started the timer, as well as the none-name product to hum. While it's not quite as loud, but clearly and consistently heard, despite the relatively loud notebook fan! A real shame ......
