Electric relays. Device, principle of operation

The book describes the device, principle of operation and the use of electrical relays of all basic types, both common and few known. By the breadth of this topic, the book is unique and in this sense is the first illustrated encyclopedia of electrical relays.
Considerable attention is paid to the history of the creation of a relay of various types, which is usually not always known to those skilled in the art, although it is interesting in itself, and her knowledge almost always emphasizes the competence of a specialist.
When considering certain types of complex relays, for example, electronic, the adjacent issues of the device and the principle of operation of the relay components are also considered (in this case of vacuum, gas-discharge and semiconductor devices), which allows the reader to understand the principle of action of the described relay without the need to appeal to additional Sources.
The book is written by a clear and affordable language, without the use of the mathematical apparatus, but at the same time supplied with plenty of illustrations (over 1000), which makes it attractive not only for specialists in the relay area, but also for a wide range of engineers, technicians, students, Wishing to replenish their knowledge about electric relays. Lecturers of courses and university teachers will find a lot of valuable material in this book for their lectures.
It is recommended to students and teachers of universities and custody, specialists from research institutes, KB and other enterprises, as well as libraries of enterprises and educational institutions
