Cole Hersee Rocker Switch On-off Spst 12V 25A 58328-100BL

The Cole Hersee rocker switch, part number 58328-100BL, is a 12V SPST on-off switch with contacts rated at 25A at 12V DC. It uses a snap-in surface mount design and a 21mm x 37mm mounting hole, which makes the opening size an important check before installation.

This switch has 3 blade terminals and 2 positions, with illuminated operation and four coloured LED lens options: red, clear, green and amber. The black plastic housing keeps the unit practical for common automotive electrical layouts where a tidy, sealed panel switch is needed.

The switch is sealed to IP66, so it is designed for use where dust and water resistance matter. As with any electrical switch, the key buying checks are the mounting dimensions, terminal style, voltage rating and the application’s current demand.

Micks Gone Bush supplies this Cole Hersee switch as an each item, with a one year warranty listed. If you are replacing an existing switch, matching the part number and physical size is the safest way to avoid unnecessary modification.

Application and Buying Notes

Before ordering, confirm the switch opening measures 21mm x 37mm and that your panel accepts a snap-in surface mount. The listed mount diameter is 21mm and the mount length is 36mm, so both the shape of the opening and the available panel space need to suit the switch body.

Check that your circuit is a 12V system and that the load is within the 25A rating at 12V DC. A switch rated for 25A still needs to be matched to the actual electrical load in the application, including how the circuit is wired and whether any relays are used.

The switch uses 3 blade terminals, so the connector style on the vehicle side needs to suit that layout. If you are replacing an existing switch, compare the physical design, terminal count, position count and illumination style rather than relying on the look of the bezel alone.

Illumination is included, with four lens colour options supplied: red, clear, green and amber. If matching a dashboard or control panel, confirm which lens colour you want to use before fitting, as that is part of the final appearance and may matter for identification of the switch function.

The one year warranty is listed for this item, but correct fitment still depends on matching the part number 58328-100BL and the application details. If there is any doubt about the opening size, terminal arrangement or circuit rating, measure the existing installation before purchase.

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 58328-100BL 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 12V Multi Colour Illumination Lenses (Contacts Rated 25A @ 12V). Part number 58328-100BL 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 58328-100BL, 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.

In the absence of a verified fitment list, the safest approach is to compare the removed unit directly with the listed product details. That includes checking the housing style, pulley layout, regulator arrangement, and any visible identification numbers before supply is approved.

The listed warranty is One Year. Warranty terms should be considered alongside correct application and part identification, as warranty does not replace fitment confirmation.

Compatibility note: Please confirm fitment by checking part number 58328-100BL, the 12V 25A rating, the 3 blade terminals, and the 21mm x 37mm mounting hole against your existing switch and panel opening before ordering.
