What does the paper present?

The catalog presents a vast collection of relays typical of the 70s and 80s. Many of the manufacturing techniques of that time are still preserved today but on a smaller scale and using other types of materials.

The document is recommended for electronics enthusiasts, who want to understand in detail the functionality of industrial relays.
