In our case, it could be called the "would be scammers" switch. The one and only time our rig was towed in (serpentine belt), we spent the night in a motel. Upon returning to the garage in the morning, the service manager said, "Well, you have a lot MORE problems than that belt." You have NO POWER anywhere now. Nothing works, no lights, etc. DH asked, "Did one of your guys hit the 'salesman's switch"? NONE OF MY GUYS TOUCHED ANYTHING. YOUR COACH HAS A SERIOUS PROBLEM. At that point we were standing by the coach door and Terry reached around and flipped that switch. EVERYTHING powered up. Terry said, "Imagine that!" The service manager walked away. Once the belt was done and several other sales thingies were tried and failed, we left.
I have heard it called both. DH says the "salesman switch" was called that because on lots where folks are allowed to walk through coaches, they flip on lights, etc. Instead of sending a employee through every coach to flip off every switch that might be turned on, they hit the "battery disconnect" to shut everything off. . . hence the "salesman switch." Don't know if that is actually how it originated, but that's what we've always heard in northern Indiana, RV Capital of the World.
