Mounted between the battery and electrical system, this switch allows the operator to shut off power to prevent drain or isolate the system during maintenance. It’s a straightforward component, but one that plays a role every time electrical power needs to be controlled at the source. When installed in the circuit, the Cole Hersee M-284-BP gives a clear on-off point between the batteries and the rest of the truck.
