Relay Logic

newbie123

Hello,

I have two 120V sources. One is inverter and one is normal AC from sticking contact. And i want only one of them as output. Output will be from inverter or 120V from sticking contact.

I want normal AC from sticking contact to be active. If it is shutdown so i want output will automatically switched over to inverter. And if 120V from sticking contact is back so i want it automatically switch to 120V sticking contact.

I have thinked to use relays, but need some help. How to design it out.

Thanks

Playing with 120V ac is pretty dangerous, you better watch out. Does it need to be controlled by a low DC current or will a switch work?
