Cole Hersee Compact Battery Switch - 150A

The Cole Hersee Compact Battery Switch – 150A is a lever-actuated master disconnect designed for high-amperage 12V electrical systems in vehicles, marine applications, and portable power setups. Built with upgraded M10 contacts rated for 150-amp continuous loads, this switch delivers robust performance without compromising the compact form factor that makes it practical for tight installation spaces. The removable lever handle and protective rubber cap enable safe isolation of battery power in field conditions or emergency scenarios.

The 150A rating represents a significant step up from older compact designs, accommodating modern vehicle electrical demands including aftermarket lighting, auxiliary power systems, and winch circuits without voltage sag or contact degradation. M10 terminals accept standard battery cable lugs and remain accessible for quick disconnect and reconnect operations. The plastic body resists corrosion in humid or salt-air environments common in coastal and offshore work, while the included rubber cap protects the switch contacts when the handle is removed—a critical detail for unattended vehicles or equipment stored in unpredictable conditions.

This switch suits operators running secondary power systems, off-road recovery vehicles, maritime patrol craft, and emergency service vehicles where rapid battery isolation is necessary for safety or maintenance. LEOs and technicians favor the Cole Hersee platform for its reliability under thermal stress and its straightforward lever interface that functions without fumbling in low-light or gloved conditions. The combination of 150A capacity and compact dimensions makes it a standard choice where space is limited but amperage demands are substantial.

Battery switches in this class serve three core functions: isolation during maintenance, load shedding in low-battery scenarios, and emergency power cutoff. The 150A rating ensures the switch will not be a limiting factor in modern electrical architectures, and the M10 contact geometry is industry-standard for marine and automotive applications, simplifying sourcing of compatible cables and adapters across multiple platforms.
