Had a chance to use our 'salesman' switch today. I wonder if yours works the same. The switch has a locking button so you can't turn the switch off inadvertently. The switch will 'maintain' itself in the 'on' position. So far so good. So I moved the locking button to turn the switch off, and found out that the switch is 'momentary' in the off position, in other words the switch will not stay in the off position by itself. There is a nice light in the switch to tell you its in the off position, but the switch will not stay off by itself. My question is; what's the point if the switch won't stay off? We just moved the coach from a storage site with a 30a hookup to a new site without electricity, so I'm trying to cut as many loads as possible.
