Types of Relay – Different Types of Relay – Classification of Relays
Depending on the operating principle and structural features relays are of different types such as electromagnetic relays, thermal relays, power varied relays, multi-dimensional relays, and so on, with varied ratings, sizes and applications.
This video main aim is to give a brief idea about various relays that are employed for a wide variety of control applications. Some of these relays are described this video.

Never Be Without Power again.
My Three most used sayings are.
1) A house roof looks unfinished until it has solar panels on it.
2) A man is not looking after his family until he is producing his own power.
3) Solar systems can be kind of pricey at first. Having power when no one else does, PRICELESS
