You need a 6 terminal switch with 2 large and 4 small terminals
The two large terminals shut off the battery
2 small terminals shut off the alternator field
2 other small terminals ground the alternator output through a resistor to
make sure the alt stops making power.
If a standard 2 terminal switch is used, the battery will be disconnected
from the engine but the alternator will continue to make power allowing the
engine to continue running.
