With its pleasant round shape and a design featuring a pure, straightforward rotary knob, the Serie R.classic harks back to old circular switches. This collection is produced in plastic (black or white) or in combinations of plastic and glass, aluminium or stainless steel by mounting a frame of the high-quality material onto a white or black plastic base plate. A wide range of functions leads to the creation of many different versions and makes the switches suitable for many different applications.
