  • I am a total newbie here, so please forgive my simple questions. I am looking to build a relay switch that will turn off the main load when the 5V power is supplied.

    The application is I am looking to cut A/C line power to a trickle charger for a generator battery when the generator is running.

             House A/C ----> Relay  ----> Trickle Charger
                               |
    

    Generator –> DC Transformer –|

    The instructions for the trickle charger indicate that the charger should be removed when the generator is running. So currently, I have to unplug the charger before starting the generator, and I want to remove that step to simplify startup for my family.

    My question is, can this project be retrofitted to allow the 5V current to turn off the main load, rather than turn it on? If not, is there a similar project (or finished product) that I should consider?

    Thanks!
