Heavy-Duty 600A Battery Selector Switch with 1-2-Both-OFF Functionality: Manage dual battery systems with reliability and precision
The ASW-A720S Battery Switch 600A, 1-2-Both-OFF, M10 is a professional-grade rotary battery selector switch built to meet the demands of marine, automotive, solar, and industrial power systems. Designed for high current loads up to 600 amps continuous, this switch allows safe and efficient battery isolation or selection between two power sources. With four selector positions—Battery 1, Battery 2, Both, and OFF—users can control and distribute power according to operational needs without interrupting the system.
Engineered for long-term reliability, this switch features corrosion-resistant materials and robust M10 terminal posts for secure connections. The rotary dial ensures smooth operation with a firm locking mechanism, reducing accidental switching or arcing under load. Its waterproof housing and compact design make it suitable for installation in harsh, space-constrained environments such as boats, RVs, trailers, and off-grid solar setups.
