    Hmmm, don't know where you came up with those ideas. Your right about
one thing, their not cheep...but do you really want a cheep switch
controlling all the power in your car? Light weight? Hell they weight a few
ounces more than the cheepies. Rated at 250 amps continuous and 2,500 amps
for 5 second surge. Sure beats the 30 amp rating on some of the cheep units
out there. And for complexity, well I don't see how it gets much simpler
than an off and on switch.
