Cole Hersee Manual Battery Switches: Heavy-Duty Disconnect Built to Last
When it comes to shutting down a vehicle's electrical system with confidence, few names carry as much weight as Cole Hersee. Since its founding in 1924, Cole Hersee has been a pioneer and leader in the development of heavy-duty electrical products for the vehicle industry, and nowhere is that legacy more apparent than in their line of manual battery switches.
What Cole Hersee Manual Battery Switches Do
These battery master switches shut down a vehicle's electrical system by cutting off current from the battery, and are designed to help prevent tampering, theft, battery drain, and electrical fires. Whether you're securing a work truck overnight, performing electrical maintenance on heavy equipment, or protecting a marine vessel from parasitic drain, a manual battery disconnect switch is an essential safety component.
SPST and DPST Configurations
Cole Hersee manual battery disconnect switches come in both Single Pole Single Throw (SPST) and Double Pole Single Throw (DPST) configurations, giving technicians and operators the flexibility to match the switch to their specific electrical system. They are available with brass or plated steel cases and are actuated by lever or hencol key, with contacts made of either silver or copper, and O-rings featured in the operating shaft of some models for additional moisture and dirt protection.
Built for Demanding Environments
For over forty years, Cole Hersee has been manufacturing heavy-duty battery master switches that have been installed as OE equipment by leading manufacturers of heavy-duty vehicles. The TR Series raises the bar further: ingress protection to IP67 and IP69K means the switch can be mounted in exposed locations on the vehicle, and it serves as a drop-in replacement for competitive master disconnect switches with higher vibration and shock capabilities.
Some models can switch two vehicle voltage circuits simultaneously — such as 24V and 12V — and are capable of disconnecting a battery or multiple batteries in either the positive or negative line. Direct lockout/tagout capability in either the On or Off position, compatible with a padlock or hasp, is also a standout feature.
Suitable applications include heavy-duty mining and construction vehicles and other off-road vehicles, as well as marine platforms where all Cole Hersee switches are designed to endure extreme marine conditions, offering exceptional resistance to corrosion, UV rays, and vibration.

With a patented weld breaker safety feature and integrated lockout/tagout, the 75930-Series Battery Master Disconnect Switch with Auxiliary Contact is designed for safely cutting off battery power to all electrical systems aboard heavy-duty vehicles and equipment used in mining, agriculture, construction, and transportation. This level of engineering detail is a hallmark of what separates Cole Hersee from generic alternatives.
