BATT ISOLATOR SWITCH 2POS 275A W/AFD

The switches themselves are very durable and rated for massive output. They feature removable windows on all four sides to cater for whatever cabling arrangement you have. Alternator Field Disconnect (AFD) protects your alternator when switching batteries in and out of the circuit. By disconnecting the alternator moments before the battery (moments after when re-engaging), there’s always a load on the alternator to protect the regulation circuitry.
