What is a relay?

A relay is a switch that opens or closes switching contacts using an electromagnet. The relay is a frequently used component in digital circuits and can switch a much higher voltage with a relatively small voltage. A relay has two important components: the coil and the switch.

How does a relay work?

The most important part of the relay is the coil. This creates an electromagnetic field when voltage is applied to it. This changes the relay into a switch. The electromagnetic causes the iron core in the coil to become magnetic, which attracts the metal armature towards it. This armature then connects to one of the contacts. When the voltage is removed again, the armature returns to the initial contact.
