EGIS 8710-1900 500A Battery Switch/Mechanical Contactor

The EGIS 8710-1900 500A Battery Switch/Mechanical Contactor is an essential component for high-amperage electrical systems, particularly in custom automotive builds, performance vehicles, and specialized off-road applications. This heavy-duty mechanical contactor acts as the master disconnect and load-control hub between your battery bank and auxiliary systems, such as winches and compressors.

Designed for continuous 500-amp operation, the 8710-1900 utilizes proven mechanical contactor technology, which eliminates electronic failure points typically found in solenoid-based switches. This design ensures reliability in extreme environments, high-vibration platforms, and temperature fluctuations. The compact footprint of 0.9 lbs allows for easy installation in engine bays, under-seat compartments, or custom battery boxes.

Ideal for truck builders, off-road enthusiasts, and mobile technicians, this switch is perfect for integrating secondary battery systems or custom electrical load management setups. Its manual operation mode provides emergency isolation, while its robust design ensures it can handle the demands of sustained high-amperage loads effectively.
