You can see from the terminals on the back of the switch that it is a Single Pole Single Throw (SPST) and from what you stated a momentary SPST. The switch you are talking about is a Single Pole Double Throw (SPDT). The SPDT has three terminals on the back of the switch which this one does not have. Check this video out on Carling switches.At the gen i flip the switch on the rear of the gen switch panel to on and then start the gen from the panel on the gen.. it will run all day until I press the stop switch. If i flip the switch on the rear of the rear of the gen to off it will start from the salon panel if I go through the start sequence. It runs for a few seconds then dies. I am still questioning the correct position of the rocker switch after the generator starts from the salon. I don't understand why it springs to the down position which I believe should be the off position.
