Electromagnetic Relay

A relay is an electromagnetic switch used to switch High Voltage or Current using low power circuits. For example, we can use it for controlling home appliances with a normal low voltage electronic circuit. Electromagnetic relays uses an electromagnet to operate a switching mechanism mechanically. It also provides isolation between low power circuit and high power circuits. Relay Internal Diagram The construction and working of a relay can be understood from the above diagram. The main part of a relay is the electromagnet. The [...]
