The Cole Hersee brand has been a pioneer and leader in the development of heavy-duty electrical products for the vehicle industry – collaborating on many industry standards and earning a reputation for quality and value.
In 2010, Cole Hersee became part of Littelfuse. This strategic acquisition not only strengthened Cole Hersee’s capabilities but also extended its reach and resources. Under the Littelfuse umbrella, Cole Hersee continues its legacy of excellence while also innovating and expanding its product lines.
As we celebrate 100 years of innovation, dedication, and success, the Cole Hersee name continues to stand for quality, reliability, excellence, and forward-thinking solutions.
Every product is built to withstand vibration, extreme temperatures, corrosion, and heavy use.
Search by part number, category, or keyword to find spec sheets, drawings, and certifications instantly.
Designed and manufactured by Littelfuse with strict quality standards and low failure rates.
Used across mining, commercial fleets, construction, agriculture, marine, and specialty vehicles.
From switches and solenoids to disconnects and wiring systems, our solutions are built for demanding environments. Each product is engineered for high current, heavy vibration, wide temperature range and long life.
Cole Hersee have been manufacturing reliable electrical switches for vehicles for close to 90 years, and throughout history have been recognised for innovative products. Some innovative switches have been awarded patents.
Many of the electrical and electronic switches and connectors made today are specified by OEMs, or used as high-quality replacement parts. Although 1924 is taken as the date Cole Hersee was established, antecedents go back even further to the dawn of the automobile age: The Henry Cole Company of Boston was founded in 1914!
Cole Hersee manufactures heavy-duty electrical components including switches, solenoids, relays, and circuit protection devices.
They are used across automotive, heavy-duty, marine, agricultural, industrial, and specialty vehicle applications.
Yes. They are engineered to withstand extreme vibration, moisture, dust, and high electrical loads. Many feature potted interiors, heavy-duty alloy or steel housings, and IP-rated sealing (such as IP66).
Cole Hersee products are available in common system voltages, including 12V and 24V, depending on the series.
Electrical ratings, dimensions, and application details are provided on each product’s datasheet.
