Regardless of the network energy, an alternative resource is needed to detect the state of network energy by detecting a switching device to activate the alternative source. There are various applications for the transfer process between network and alternative source. These applications include more complex applications using more than one circuit elements such as compact switch and mechanical locking block, and more complex applications using more than one circuit elements such as Enversor Controllery application.

Energy continuity is very important hospitals, educational institutions, factories, airports and so on. A smooth and fast switching unit becomes important for providing emergency energy needs in such areas.

Automatic transfer switches are the device that automatically activates the other energy source if the source is cut from 2 energy sources. The main compact structure consists of electronic control unit, mechanical lock and 2 different differentials.
