In this series, the inserts are covered by an almost color-neutral special glass, the edge of which almost disappears in a highly polished facet cut of 45°. The robust physicality of the Bakelite / Thermoset switches is visually diminished, which is further enhanced when the wall covering is pulled under the glass cover (this requires a little more care during installation). You can use the new covers with all switchgear and all junction boxes. Again, there are system covers to set the switches on top of and below each other, but no multiple covers. All glass parts come from one of the former many glassworks in the Upper Palatinate Forest. The glass panes are 4 mm thick and thermally tempered, and of superior transparency.
