A Mechanical Sewing Machine (also called an Electromechanical Sewing Machine) is a Sewing Machine with an electric drive and mechanical control, that is, which uses knobs and dials to adjust the stitching parameters.
Mechanical sewing machines do not have a very wide variety of stitches, but they are quite easy to maintain and use, and also cost less compared to Computerized Sewing Machines.
However, this type of sewing machine ranges from fairly simple models for beginners to powerful and high-speed models for professionals.
