    Default Turn off one device when another goes on

    I need to turn on off one appliance when another turns on and vice versa automatically. Both use 12v transformers and do not have on/off switches so cutting or providing power is all that is needed. I could use a timer on each but would like a more elegant solution.

    Default Re: Turn off one device when another goes on

    IT, do the appliances turn on/off automatically or are they controlled manually.

    If the latter, a simple 3 way switch in a junction box would work.

    If the former, a current sensing relay will be required, and a larger control box.

    Good Luck from Columbiana, Alabama
