Two things:
Not disputing the point, but I was always told to put the switch on the
ground side. What is the reason for sayng it should be on the
non-ground?
A good way to keep the radio presets from going away is to wire a VERY
low value fast-acting in-line fuse across the switch. You open the
switch, and power is available to keep the presets alive through the
fuse. Anything starts drawing real power (even a dome light bulb, if
you put in a low enough value fuse) and the fuse blows and the circuit
is open. Another way is to have a 9 volt battery wired to a cigarette
lighter plug. Plug that in to the cigarette lighter just before
throwing the switch. 9 volts is enough to keep the presets alive.
