The Cole Hersee 75910 Battery Master Switch provides dependable manual isolation of a vehicle's battery and alternator or generator field circuit. Its DPST on/off configuration allows the main battery circuit and field circuit to be controlled together, supporting a complete electrical shutdown in compatible heavy-duty installations.
Designed for 6–36V DC systems, the switch is rated at 125A continuous on the main battery circuit and 20A continuous on the field terminals. Silver contacts, a heavy-duty plated-steel casing and a chrome-plated lever support reliable switching in commercial vehicle, mining, plant and equipment applications.
The brass indexing pin aligns the switch and helps prevent rotation after installation, while an O-ring seal provides weather resistance around the mounting shaft. Confirm the electrical ratings, cable requirements and mounting dimensions against the application before installation.
