THPG 184209 Pull switch alternation surface mounted bakelite

184209 - Pull switch alternation surface mounted bakelite.‎ Technical features - 10 A, 10 AX, AC 250V - Bakelite housing and pull switch insert - This switch can be used if you use one or two switches for one lamp - Suitable for wall and ceiling installation - Note: A base plate is essential for easily inflammable or uneven surfaces 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.‎‎ Further info from manufacturer on 184209 THPG
