Cole Hersee Single Pole Brass Battery Switch w/Faceplate 175 Amp Continuous 800 Amp Intermittent

The Cole Hersee Single Pole Brass Battery Switch with Faceplate is the marine-grade master disconnect switch every serious boater needs for reliable electrical system protection. Whether you're running a center console, cabin cruiser, or multi-engine fishing platform, this UL-listed switch isolates your battery bank instantly in emergency situations or during maintenance. Built by Cole Hersee—a name trusted in marine electrical systems for decades—this switch handles the demanding demands of saltwater and freshwater environments where electrical reliability directly impacts safety on the water.

Rated for 175 amps continuous and 800 amps intermittent operation, this single-pole switch delivers the high-amperage capacity modern boats demand when running thru-hulls, trolling motors, GPS systems, and marine air conditioning units simultaneously. The brass construction resists corrosion from moisture and salt spray far better than steel alternatives, extending service life in harsh marine environments where oxidation compromises electrical connections. The integrated faceplate mounts flush to your panel, providing a clean installation while the two-position toggle mechanism offers instantaneous on/off control—critical when you need to kill power before troubleshooting or securing the vessel.

Anglers and boaters with 6V to 36V DC systems benefit most from this switch's versatility, whether powering a single battery or managing multi-bank configurations on larger vessels. Installation fits standard marine electrical panels, and the compact 1 lb weight keeps it ideal for retrofit applications on existing boats. Coast Guard and marine insurance underwriters recognize UL-listed master disconnect switches as essential safety components, making this Cole Hersee unit a code-compliant choice for any vessel requiring documented electrical safety compliance.
