Electronically Operated Relays & Their Types

A relay is an electronically operated switch that is used to control an electronic circuit by a separate low-power signal. Relays use an electromagnet to mechanically operate a switch which is either breaking or making electric circuits by their output section. A large number of relays used in electrical applications where one electric circuit is being energized by the presence of a specific voltage that is actually provided by another circuit.
