Running two batteries in a caravan or work truck and you need a switch that won't crack under load? This one's moulded in Bakelite plastic. Not a marketing word – it means heat-resistant, tough, built for sustained current. Handles 175A continuous, 300A intermittent on 12V or 24V systems. Three connections: Battery 1, Battery 2, Common. Large brass 10mm studs. Red locking lug stops accidental position changes. Note: this unit has been replaced by SF2451 – confirm that part number before ordering. Add to cart
