Electronic – Auto turn off switch during power outage

home-automationsurge-protectionswitches

In my area power outages are a daily routine. And power surges, which occur when the electricity comes back, makes it even worse. To avoid damage of the electronic devices we try to unplug them quickly. However, if we are out of the house, this is not possible.

So, I was thinking of some sort of "automatic switch" which disconnects the device from its power source by opening the circuit when there is a power outage, and which requires human action to turn back ON again.

Is there any simple switch or device that can do this task?

You could also use a 12Vdc relay powered by small 12Vdc on the power strip to drive coil. But then you need a 12V bat to Reset
