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.
