Electromagnetic and electronic relays. Part II: electronic switch

Abstract

The relays are devices designed to produce certain modifications, when certain conditions in an electrical circuit that influence him in the same circuit or in another. The circuit acts on the relay acts as a control or signaling. Is the world of industrial automation systems. The electromagnetic relay function is similar to the electronic switch control circuit and the contactor for power circuits. But in terms of its constitution, the differences are notable because they have moving parts, or even consist of a single piece.
