About This

Streamlined Switch Design: The 1-Both-2-Off knob switch is a 4-position selector switch. It allows for switching isolated battery banks to all loads or combining battery banks to all loads. Comes with 4 screws
Uninterrupted Power Switching: The make-before-break contact design allows for switching between battery banks without interrupting the power supply
Superior Quality: Constructed with high-quality ABS plastic for the housing and tinned copper studs, this design prevents battery switch leakage, protects the power supply, and safely disconnects the battery
Spark-Proof Design: Featuring an ignition-proof design, it can be safely installed on gasoline-powered boats. The chassis design supports surface, front panel, or rear panel mounting. Suitable for yachts, RVs, off-road vehicles, modified vehicles, and ATV UTVs
Safety Protection: With a continuous rating of 350A—70% higher than standard switches, and a maximum voltage of 48V DC, it eliminates any power draw from the battery when vehicles or boats are not in use, ensuring a safe disconnection.
