Product Overview
A stored vehicle that keeps waking up to a dead battery, or a custom electrical system that needs a clear shutoff point, can benefit from a manual master disconnect. The switch must still be sized and wired for the actual load.
The switch opens the battery circuit to reduce storage drain and isolate power. It must be sized for continuous and starting current and installed with protected battery cable.

Frequently Asked Questions
Q: Will this cure a parasitic draw? A: No. It prevents discharge while open, but the electrical fault still needs diagnosis.
Q: Should it go on the positive or negative cable? A: Follow the switch and vehicle instructions; many simple storage disconnects use the negative cable.
Q: Can it be switched off while the engine runs? A: Do not do so unless the system is designed for load disconnection.
Q: Will radio settings be lost? A: Possibly. Battery disconnection can erase memories and require relearn procedures.
