The switches and sockets of the Unica range are particularly slim in construction. In the off mode, the thickness of the switches is a mere 6.5 mm. Thanks to their flat construction, the switches are barely noticeable when mounted on a wall and thus easily blend in with different styles of interior decor. Their cover is rounded at the edges, giving them a mellow appearance. It is made of anodised aluminium while the base is made of plastic, as is the isolating screw cap used for installation to protect users from possible danger.
