Frequently Asked Questions

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.

Cole Hersee manufactures toggle, rocker, rotary, push-pull, and ignition switches designed for vehicle and equipment use.

Yes, for standard, non-illuminated switches, simply halve the amp rating (e.g., a 20A 12V switch becomes a 10A 24V switch). However, illuminated switches must match their rated voltage exactly.

Calculate the total continuous current draw. When wiring commercial lighting—like the upgraded CISPR 25 compliant EW2601 series beacons. Always select a switch with an amp rating that slightly exceeds the total load to minimize heat and extend the switch’s lifespan.

Many switch models are designed to handle high current loads. Always refer to the product’s amperage and voltage ratings.

When electrical ratings and mounting configurations match, Cole Hersee switches are commonly used in replacement applications.

Cole Hersee offers solenoids for starting, battery management, and power switching applications.

Continuous-duty models can remain energized indefinitely for powering auxiliary systems. Intermittent-duty models handle massive power spikes for short bursts (like starter motors) and will overheat if left on continuously.

Certain relay models are designed to manage high current loads. Refer to datasheets for load and duty ratings.

Cole Hersee manufactures circuit breakers and battery disconnect switches designed to protect electrical systems.

They isolate electrical systems for servicing, storage, or emergency shutdown. Use SPST switches for basic isolation or DPST for more complex setups. For strict site compliance and fleet safety, select models featuring integrated lockout/tagout capabilities.

Cole Hersee offers both manual-reset and automatic-reset circuit breaker options, depending on the application.

Selection should be based on system voltage, current rating, environmental exposure, and reset requirements.
