Over-centre rotary switch alternation bakelite
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. This is due to its production. Instead of being produced using the injection-moulding procedure, bakelite is moulded directly from its raw form using the “matrix method”.
With the successful development of the porcelain switch system, we have set out to restore this harmonious coexistence. In close cooperation with the company CAW, we have brought the lost moulds and tools back into production and have found material manufacturers who are masters at processing bakelite – a skill which can no longer be taken for granted. The result is the bakelite switch system: just like its porcelain counterpart, it is both functionally and aesthetically superior to other synthetic mouldings.
