Finally found what I was looking for my RV as in a switch to run some lights and a heating pad for my potable water tank. There is no template but made one out of construction paper. I had a question on using one of the switches as a power switch and the answer helped me. So to turn on the unit I push the far right switch then can use the other three switches for my lights / heater. I love the option of having usb for phones and the battery readout which my RV does not have.
