Cole Hersee Rocker Switch On-off Spst 12V 25A Red Illuminated Part No. 58328-04BL

The Cole Hersee rocker switch listed here is an SPST on-off switch rated at 25A at 12V DC, with red LED illumination and a black plastic housing. It uses 3 blade terminals and is designed as a snap-in surface mount switch with a mounting hole size of 21mm x 37mm, making the physical opening a key check before purchase.

This switch is identified by part no. 58328-04BL and is supplied as a 12V rocker switch with 2 positions: on and off. The sealed construction is rated IP66, which is an important point for buyers looking for a switch that can better resist dust and water exposure in vehicle and equipment installations.

For anyone replacing an existing switch, the main compatibility checks are the 12V electrical system, the SPST on-off action, the 25A current rating at 12V DC, and the 21mm x 37mm mounting hole. Those details matter as much as the external style, because a rocker switch can look similar but still differ in terminal layout, cut-out size, or electrical rating.

Application and Buying Notes

Before ordering, confirm that your panel or dash opening is sized for the 21mm x 37mm mounting hole and that you have room for the 36mm mount length. The switch is a snap-in surface mount design, so the cut-out shape and available depth should match the existing installation rather than relying on the face style alone.

Electrical matching is just as important. This model is rated at 25A at 12V DC and is an SPST on-off switch with 1 pole and 2 positions. That makes it suitable only where the circuit calls for a simple on/off function at 12V, and where the current demand stays within the 25A rating.

The 3 blade terminals should also be checked against the existing wiring plug or terminals in the vehicle or machine. If you are replacing a switch already fitted with a different terminal arrangement, the part may not connect without modification, even if the cut-out size looks correct.

The red LED illumination is useful where a visible switched-on indication is wanted, but it should still be treated as a compatibility point rather than a reason to choose the switch by appearance alone. The key purchase checks remain the part number 58328-04BL, the 12V system requirement, the SPST on-off action, and the IP66 sealed construction if the switch will be used in a location exposed to dust or moisture.

If you are unsure about the original switch, compare the old unit carefully against these details before fitting a replacement. Matching the part number, voltage, pole count, terminal count, and cut-out dimensions is the safest way to avoid ordering the wrong switch for the application.

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 58328-04BL 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 Red Illuminated (Contacts Rated 25A @ 12V). Part number 58328-04BL 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 58328-04BL, 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.

Compatibility note: Confirm fitment by comparing part no. 58328-04BL, 12V operation, SPST on-off function, 3 blade terminals, and the 21mm x 37mm mounting hole with your existing switch and panel opening before ordering.
