Hello I recently bought this item at ebay and I am not sure how I should wire this.
I will power it with a 9 volt battery and the relay will power a pump, this is how they at ebay show how I should wire it. But I don't understand how I will connect my pump's positive and negative wires to the circuit or how I will connect my 9 volt battery to the circuit?
Since the (X) symbol on the chart is only powered by a negative wire from what i can understand. DC-
and from my basic knowledge the (x) symbol is a lamp? (the source that needs power)
I also don't understand what the two power terminal at the top will do that has nothing connected to it?
What this circuit will do is that it will delay my push button action so the power will remain on to the pump for 5 seconds then turn of instead of the push button will only power while pressed.
