Cole Hersee Rocker Switch On/off Spst 25A 12V Part No. 58027-01BL

The Cole Hersee rocker switch is a non-illuminated, On-Off SPST switch rated at 25A at 12V, with part number 58027-01BL. It uses a 3-terminal layout and is supplied as a single switch, so it suits replacement work where the existing switch style, electrical rating, and terminal count need to match closely.

This switch has a 21mm mount diameter and a 36mm mount length, which are the key physical measurements to check before ordering. With 1 pole, 3 positions, and a rocker switch action, it is designed for straightforward control applications where a simple on/off function is required.

Cole Hersee is listed as the brand, and the product sits within auto electrical accessories and fuses, breakers, relays, and switches. The switch is covered by a one year warranty, which gives a clear reference point for buyers looking for a defined replacement part rather than a universal guess.

The lamp colour is listed as not applicable because the switch is non-illuminated. That matters if you are replacing a lit switch, since the face style and electrical setup need to be confirmed before fitting the 58027-01BL into the panel opening.

Application and Buying Notes

Before buying, check the part number 58027-01BL against the switch you are replacing, then compare the 21mm mount diameter, 36mm mount length, and 3-terminal layout. Those physical details are often the quickest way to rule out a mismatch before the panel is removed or the wiring is disturbed.

The 25A at 12V rating is an important guide to electrical suitability. A switch used in a lower-duty circuit may be fine from a rating point of view, but the opposite is not true, so the current and voltage needs of the circuit should be confirmed against the existing installation or the component being replaced.

Because this is a non-illuminated rocker switch, it will not suit every dash or accessory panel where a lit switch was originally fitted. The lamp colour is listed as not applicable, so buyers should check whether the existing switch has backlighting, an indicator lamp, or any other visual function that must be retained.

The switch is identified as On-Off SPST with 1 pole and 3 positions, which points to a simple single-circuit switching arrangement. If the current switch has additional functions, different terminal counts, or a different switching action, the physical fit may look similar while the electrical operation is not the same.

If you are replacing a damaged switch, it is worth matching the panel cut-out measurements, terminal arrangement, and the position style before finalising the order. Those checks are especially useful when the vehicle or equipment application is not clearly labelled and the switch has to be identified by its dimensions and part number.

The one year warranty provides a defined purchase period, but it does not replace the need to confirm suitability for the intended circuit. A careful check of the existing switch, the mounting opening, and the wiring terminals is still the best way to avoid downtime and unnecessary returns.

Before supply, the safest approach is to confirm the original unit details against the listed part number, voltage, output rating, mounting arrangement, and pulley configuration. That checking process is standard practice in the parts trade because visually similar units can still differ in service-critical ways.

For workshop, fleet, and equipment applications, accurate identification of part number 58027-01BL helps avoid unnecessary freight, additional labour, and vehicle or machine downtime. Where the application is not straightforward, the original unit, OEM reference, or workshop records should be used as the primary confirmation point.

Cole Hersee Rocker Switch On/Off SPST (Contacts Rated 25A @ 12V). Part number 58027-01BL should be checked first. Listed voltage is 12. Listed output rating is 25. These details form the core reference points used by parts interpreters when confirming the correct replacement.

For part number 58027-01BL, the normal identification sequence is part number, electrical rating, mounting arrangement, connector or terminal style, and pulley or drive details. Using those checkpoints helps confirm that the listed unit matches the service requirement rather than only looking similar.

For a switch in workshop, fleet, trade, agricultural, or construction service, the listed voltage 12 and output 25 should be checked carefully. Incorrect selection can affect installation time, return freight, and equipment availability.

Where no verified application list is available, the part number, mounting details, connector style, and published specifications should be used as the primary selection criteria.

Compatibility note: Confirm compatibility by matching part number 58027-01BL, the 21mm mount diameter, 36mm mount length, 3-terminal layout, and the 25A at 12V rating against the existing switch and application before purchase.
