The battery switch is to be mounted in a readily accessible location as close as practical to the battery. First of all, I do not know how to comply with the 7 inch rule. The best I can do is about 18 inches to get from the battery terminal to outside the battery box where it connects to a surface mount 300a fuse. Secondly, I consider the battery switch being mounted in a readily accessible location more important than being close to the battery. >> Gary, Your situation is similar to mine. On another list, Arild suggested using a mechanical (Bowden) cable to operate a battery switch. In my boat the master battery disconnect is a large knife switch, purchased years ago from J. C. Whitney. The switch is mounted next to the battery terminals. The handle of the knife switch is connected to a metal rod which extends about 2 feet to the outside of the battery box. It is terminated in an easy to grab knob. To disconnect the battery the knob is pulled about 2". The switch opens. No relays, no rotary switches - just 19th century simplicity. Larry Z
