Today we are introducing a new way to make an auto change over
with the help of 8 pin Electromagnetic relay .
Change over is a switch which is used to transfer load from one supply source to another source e.g from electric supply company to generator or another feeder .
i also explain the working and connection of 8 pin electromagnetic relay in great detail.
normally manual changer over's are used in our daily life which are the old way to transfer load from on supply source but in modern life this is done by auto change over.
this is very simple circuit which is easy to understand and design such a circuit without any knowledge of electrical.
