About This

Stop Battery Drain, Fast Control – This battery disconnect switch gives quick ON/OFF isolation to stop parasitic draw during storage or service. A simple twist protects your system and works as a reliable battery kill switch for safety
Heavy-Duty Performance – Built for 12–48V DC systems: 275A continuous, 455A 5-min intermittent, 1250A 10-sec momentary. A true car battery disconnect switch for cars, trucks, RVs, marine boats, and off-grid/solar setups
Premium Materials for Long Life – Rugged PBT housing resists heat and deformation; thick tinned-copper studs (3/8”/10 mm) deliver low-resistance, corrosion-resistant connections. Use heat-shrink on ring lugs for extra short-circuit protection
Installation tips for safer routing — The compact square base supports surface or panel mount. To further eliminate short-circuit risk, don’t route both cables through the same pass-through. Run them from opposite directions and keep separation, and use heat-shrink tubing/insulating sleeves plus cable ties for secure, tidy installs in tight engine bays or battery boxes
Fitment Tips – Designed for stud/ring-lug connections (3/8” ring terminals). Measure cable lugs and installation space before ordering to ensure a perfect fit
