Electronics manufacturing technology

Electrical devices are electrical devices designed to change, adjust, measure, and control the electrical and non-electrical parameters of various devices, machines, mechanisms, etc., as well as to protect them from overvoltage. According to its functions, it is divided into switching, commissioning, corrective, restrictive, measuring, control. Depending on the physical phenomenon on which the work is based, electrical devices can also be divided into electromagnetic, thermal, induction and other types. Sometimes the operation of one device is based on several physical phenomena.
