Reply With QuoteIf i'm following what you said corectly it shouldnt matter which way you connect the inverter, just like a normal switch it dosent really matter which way around you connect it (unless of course you are using the NC contact as well)
I can't find the original forum but I'm adding a 12v .5 amp at 125vac SPST relay to the on/off switch of my inverter so it powers up with the Ignition.
But I don't exactly know which pins on the relay get soldered to which wires in the Inverter.
The top of the switch has a " l " mark, and the bottom of the switch has a "O" mark. So does the " l " mark match the + of the inverter switch? or does the + come in to the inverter through the "O" mark on the inverter switch?
Pressing the " l " part of the switch will turn the inverter on, but that still doesn't tell me which way the electricity is flowing. From " l " to "O" or from "O" to " l ".
I know my question is confusing, but I hope somebody followed what I said.

Newbie Question - hardwiring inverter w/ switch..please help
Halfway down VCBB5 posts a diagram that I am following. Basically, I need to solder to the "HOT" 12v lead that comes from the battery before the switch because the other side of the switch has no power. I just can't determine which side of the switch is truly coming from the Battery. " l " or "O".
err what? It should work either way, just connect the invertor to one of the terminals and 12v to the other.

Wonderworm, relays don't have polarity - all it's doing is connecting two pieces of metal, so it doesn't matter which way the current flows across it.
If someone could tell me exactly which connections go to where I would very much appreciate it.
Is this how I connect it? Also, can I just use the ground (3rd prong on AC plug) inside the inverter as a ground? Or do I need to run the relay's ground to the car frame?
is that a rocker switch or a momentary switch?
assuming its a rocker switch it dosent matter which way around it goes, connect I to one side of the relay and O to the other side, like we have been saying

Thanks for the help. All done.
Well, I thought I was all done, but the relay didn't seem to work as planned. I wired it up like the above diagram and the inverter just stayed on whether the IGN was on or off. It was just like it was wired straight to the battery and I had shorted the on off switch with no relay.
So I obviously don't know how to wire a relay to an on/off switch. Any help on where I messed up is appreciated.
