Cole Hersee Rocker Switch On/off/on Spdt 25A 12V Part No. 58027-03BL

This Cole Hersee rocker switch is an On/Off/On SPDT unit with contacts rated at 25A at 12V. It uses a 1-pole, 3-position switching arrangement and has 3 terminals, which makes it suitable where a simple maintained changeover control is required in a 12V circuit.

The switch has a 21mm mount diameter and a 36mm mount length, so panel opening size and available mounting space should be checked before ordering. It is non illuminated and lamp colour is not applicable, which is important if you are matching an existing dash or control panel layout.

Identified as part no. 58027-03BL, this switch is sold as each and sits within the auto elec accessories group. It carries a one year warranty and is listed under vehicle electrical switches and related control components.

Application and Buying Notes

Before buying, confirm that your panel is set up for a 21mm mount diameter and that the available length behind the panel can accommodate the 36mm mount length. Those two measurements are the first checks for avoiding installation issues on a rocker switch of this style.

Because this is an On/Off/On SPDT switch with 3 terminals, it suits circuits that need a maintained centre off position and two switched outputs. The 25A at 12V rating should be matched to the actual circuit load, wiring size, and any upstream protection used in the vehicle or equipment.

If you are replacing an existing switch, compare the part number 58027-03BL, the terminal count, and the non illuminated specification with the unit already fitted. A close match on the physical dimensions and switching action is just as important as the electrical rating when selecting a replacement.

This switch is listed as a single each item, so if you are updating both sides of a control panel or carrying a spare, order accordingly. As with any electrical component, the final check should be against the vehicle or equipment application and the wiring configuration before installation.

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 58027-03BL 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/On SPDT (Contacts Rated 25A @ 12V). Part number 58027-03BL 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 58027-03BL, 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: Please confirm compatibility by checking part no. 58027-03BL, the On/Off/On SPDT switching action, 3-terminal layout, and the 21mm mount diameter with your existing application before purchase.
