Protects the diodes in the alternator in the event of the switch being switched to the OFF position while
the engine is running. If the AFD is not used to protect the alternator, an LED can be connected to
the AFD terminals to indicate when the battery switch is in any position but OFF: ON for the Single Circuit 1,2, or 1+2 for the Selector - 4 Position 1 or 2 for the Selector - 3 Position

WARNING The positive and negative conductors should not be attached to the same battery switch.
The only exceptions are the Dual Circuit Battery Switches 6010 and 5510 Since these models have electrically isolated circuits and do not include a combine feature, they can provide disconnect to the positive and negative conductors simultaneously.
