ABB KALO ROTARY DIMMER has sort of a fancy name, but it's something you're probably already familiar with. It's a dimmer switch with a dial on its face. The elegance of the Kalo design series lies in its simplicity and purity. The neutral white design perfectly complements any interior, with a blue LED backlight which illuminates itself in the dark. Now you can fully devote yourself to interior design and fitting – because the Kalo design line is affordable and at the same time branded.
