Abstract
Continued development of automatic change over switch is a necessary requirement for the principle of energy mix especially in developing countries characterised by insufficient mains power supply. In this paper, we report how we were able to intuitively use basic electronic components to implement an efficient automatic change over switch. In the event of a power failure from the mains supply, this automatic changeover is designed and constructed to switch on a standby generator and transfer the installation load to it (the generator) and vice versa when power is restored. The switching time was calculated and tested to be about 0.88 ms which is sufficient to prevent any noticeable disruption in the power supply to the installation load, whether home or industrial.
