Cole Hersee

<h3>Cole Hersee: A Century of Heavy-Duty Electrical Excellence</h3><p>Few names in the commercial vehicle industry carry as much weight as Cole Hersee. <strong>Founded in 1924</strong>, the company traces its roots to the merging of the Henry Cole lamp socket business and the F.C. Hersee machine shop, a union that gave rise to one of the most trusted names in heavy-duty vehicle electrical components. For over a century, Cole Hersee has been a pioneer and leader in developing rugged, reliable electrical products engineered to withstand the punishing demands of trucks, big rigs, construction equipment, agriculture machinery, and military vehicles.</p><p>Today, Cole Hersee operates as part of Littelfuse, which acquired the Boston, Massachusetts-based company in 2010 to strengthen its commercial vehicle product portfolio. The combined expertise has only reinforced Cole Hersee&apos;s reputation, expanding its reach while preserving the exacting engineering standards that fleet managers and professional technicians have come to rely on. All Cole Hersee products are manufactured in an ISO 9001-certified facility and undergo strict quality testing to ensure safety and reliability in the field.</p><h3>What Cole Hersee Makes</h3><p>Cole Hersee manufactures the broadest range of vehicle switches, connectors, and electrical and electronic products in the heavy-duty segment. Their catalog spans rocker, toggle, ignition, rotary, push-pull, and windshield wiper switches, as well as solenoids, relays, circuit breakers, battery master switches, tractor-trailer connectors, terminal blocks, buzzers, alarms, and pilot lights. Cole Hersee is also a preferred supplier of over 2,000 dependable vehicle products and accessories, many of which helped shape the basic industry standards still in use today.</p><p>One of the brand&apos;s standout product lines is their <strong>heavy-duty battery master switches</strong> — a category where Cole Hersee has held OEM supplier status with leading heavy-duty vehicle manufacturers for over four decades. These switches cut battery current to help prevent theft, tampering, electrical fires, and battery drain, making them a critical safety component on any commercial rig.</p><p>On the lighting side, Cole Hersee&apos;s <a href="/7300-cole-hersee-roof-marker-light-10052">Roof Marker Lights</a> are a go-to choice for truck operators who need DOT-compliant, durable clearance and identification lighting. Built to face vibration, moisture, and extreme temperature swings, these lights reflect the same design philosophy that runs across Cole Hersee&apos;s entire product line: purpose-built toughness for real-world working conditions.</p><h3>Why Professionals Trust Cole Hersee</h3><p>What sets Cole Hersee apart is a combination of deep industry roots and constant innovation. The brand collaborated on many of the foundational electrical standards for commercial vehicles, and that heritage translates directly into products that integrate seamlessly with both legacy platforms and modern equipment. Whether you&apos;re maintaining a long-haul fleet, repairing a vocational truck, or outfitting specialty equipment, Cole Hersee offers both standard and custom-designed solutions to meet the application at hand.</p>

Product Details

The Cole Hersee M750BP is a marine-grade dual battery switch designed to manage power distribution between two battery banks. This ignition-protected switch allows you to control which battery or batteries supply power to your electrical system, while also providing a complete shutoff capability.

Key Features:

  • Four-position rotary switch: OFF, Battery 1 only, Battery 2 only, or BOTH batteries combined
  • Ignition protected construction meets USCG and ABYC safety standards
  • Durable plastic case with molded insulator for reliable corrosion resistance
  • Heavy-duty contacts for continuous duty rating
  • Prevents accidental battery drain when equipment is not in use
  • Allows parallel battery operation for heavy electrical loads

This battery selector switch is ideal for marine, RV, and commercial vehicle applications where dual battery management is required. The OFF position provides a master disconnect for safety during storage or maintenance. The BOTH position combines batteries for engine starting or high-demand situations, while individual battery positions allow you to preserve one battery as a backup or isolate a battery for charging.
