TrailManor
4-way (1/2/Both/Off)
Battery Switch Project

Two months prior to this project, I completed a similar project, installing a battery on/off switch on my trailer.  Since that time, my needs have changed.  I installed an electric tongue jack on my trailer.  I had been advised that when in use, some electric tongue jacks can pull enough of a load from the trailer's 12 volt system to severely damage the power converter (a Parallax 6300 in mine) in the trailer.  So I set out to wire the electric tongue jack in such a way that I would not inadvertently power the jack while the trailer's converter was active (plugged into shore power).  

I checked with the same manufacturer (Blue Sea Systems) that made the basic mini-on/off switch used in the first project.  They made a switch like I wanted but not in their mini line.  The mini-switch is about 2.5" square where their standard switch line is 3.85" square.  As luck would have it, while on the phone with a very helpful engineer from Blue Sea Systems, he told me that another company was making a 4-way switch in a mini version.  I Googled "BEP New Zealand" and found BEP Marine's website.  Researched their product, found and contacted their US distributor and ordered up my BEP Marine 701-S 4-way Battery Switch.  Below are pictures of my conversion project from the on/off switch to the 4-way switch.
