Bob,

  In case of an emergency landing  you may want to disable the electrical
system with one simple action. I am thinking ruptured fuel lines and
sparking wire here. Not a pleasant image and one that has claimed several
SeaWind owners.  Perhaps something as simple as a mechanical copper knife
switch on the main power cable near the battery would be the ticket. You
could rig a cable to activate or disable it.

the part you want is a batery isolator switch:

the corvair guys have been using them with great success.
