Solutions for lighting systems:
Porcelain, Bakelite®, Duroplast, Glass
Our switching systems made of porcelain and bakelite are
developed by THPG. They are produced in Thuringia (porcelain
covers and central inserts), in Westphalia (bakelite covers, central
inserts and switching mechanisms) and in Bavaria (glass covers).
covers made of bakelite the material walls are at least 2,5 mm thick, the glass covers 4 mm and the porcelain covers are 13 mm thick.

The inner workings are made to match: the main units for the
rotary,
rocker and toggle switches are made of ceramic material.
And: our rotary switches are still true rotary switches in which the
contacts are opened and closed through rotation. These days, that
is not always the case, many other rotary switches are really rocker
switches which are operated via a turning knob. The difference can
be both felt and heard.
Porcelain switch system
From the beginning of the electrical
age and several decades to
follow, the porcelain and ceramics industry was the most important
provider of electrical technology:
casings, switch pieces and housings
were made from this attractive
material that, apart from its
aesthetic qualities, has tangible technical benefits: it insulates and is extremely
tough.
Our porcelain switch system is now for more than ten years established
on the market. It is both functional and pleasant in three ways: to the eye,
to the touch and to the ear (thanks to the enjoyable “klack” sound of the
rotary switch).
Bakelite® switch system
Porcelain and bakelite coexisted
harmoniously for many years, and
both switch colours, white porcelain
and black bakelite, were
equally popular. The synthetic
resin bakelite was found to be an
ideal material for electro-technical
applications: its stability was unmatched
and its temperature resistance
and insulation were tremendous.
The material remained
common in light switches and
power outlets into the 1960’s, but then bakelite was replaced by cheaper
synthetic materials.
With the spread of thermoplastic as the new switch
material, bakelite virtually disappeared from the scene. However, there
is no comparison between bakelite and thermoplastic: Bakelite is much
heavier and more pleasant to the eye and to the touch. With the successful
development of the porcelain switch system, we have set out to restore
this harmonious coexistence. The result is the bakelite switch system: just
like its porcelain counterpart, it is both functionally and aesthetically superior to other synthetic mouldings.
The white bakelite switch system: duroplast
The white duroplast series corresponds
technically to the black bakelite
series. All cover plates, switch
buttons and outlet elements in the
series are made of lightfast white
duroplast.
Like in all other series, the insides of these switches originate
from CAW. As early as in 1910, CAW was granted a patent for an
electric rotary switch with a movable contact bridge on an annular
track.
The glass switch series: cut glass and bakelite
Light switches with glass covers have already existed before, in the
1930s. With our glass covers, manufactured
from a special, highly
transparent glass, switches are
rendered almost invisible. In addition,
pretreatment makes the glass
resistant to any splintering at the
edges. It is beveled at a 45° angle
and lavishly polished to ensure the perfect optical fi nish.
The switch can even be easily papered over. It does require some extra attention during installation, but the outstandingly subtle look certainly compensates the extra effort. Our covers are available in six variations and can be used with all rotary switches and central inserts from our black and white bakelite series.
