Sewing machines

Introduction of electronic machines

Sewing machines were strictly mechanical, using gears, shafts, levers, and so on, until the 1970s when electronic machines were introduced to the market. Electronic sewing machines incorporate components such as circuit boards, computer chips, and additional motors for independent control of machine functions. These electronic components enabled new features such as automating thread cutters, needle positioning, and back-tacking, as well as digitized stitch patterns and stitch combinations. Because of the lifespan and increased complexity of the electronic parts, electronic sewing machines do not last as long as mechanical sewing machines, which can last over 100 years.
