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.
