Cole Hersee Rocker Switch On/off Spst 12V Blue Illuminated 25A Part No. 58328-55BL

The Cole Hersee rocker switch, part no. 58328-55BL, is a 12V SPST on-off switch with contacts rated to 25A at 12V DC. It is supplied as a single switch unit and uses a 3-blade terminal arrangement, which is a practical detail to confirm before wiring or replacing an existing control.

This switch is a snap-in surface mount design with a mounting hole requirement of 21mm x 37mm and a mount length of 36mm. The black plastic housing and blue LED illumination make it a neat, functional choice where a compact illuminated rocker is required.

It is sealed to IP66, which gives a useful level of protection in demanding vehicle and equipment environments where dust and moisture exposure are a concern. As with any electrical control, the part number, terminal count, mounting dimensions, and switching action should be checked against the existing panel before purchase.

Application and Buying Notes

Before ordering, compare the part number 58328-55BL and the physical details of your current switch. The key matching points here are the SPST on-off function, 12V system voltage, 25A contact rating, and the 3 blade terminals. If your existing switch uses a different terminal count or switching arrangement, it will not be a direct replacement.

The mounting dimensions matter just as much as the electrical rating. This switch needs a 21mm x 37mm mounting hole and has a 36mm mount length, so the panel cut-out and available depth need to suit the rocker body and snap-in surface mount design. A quick size check can prevent installation issues later.

The IP66 sealing and blue LED illumination are useful features, but they do not replace fitment checking. LED colour, terminal layout, and mounting shape all need to match the application you are working on. If you are replacing a failed switch, comparing the old unit side by side is the safest approach.

This is a 12V switch rated at 25A, so it should only be used within the limits of the circuit and the equipment it is intended for. If the application draws close to the upper end of the rating, confirm the full circuit load, wiring size, and protection method before installation. A correct switch choice is only one part of a sound electrical setup.

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 58328-55BL 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 Blue Illuminated (Contacts Rated 25A @ 12V). Part number 58328-55BL 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 58328-55BL, 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 the part number 58328-55BL, the 12V SPST on-off configuration, the 3 blade terminals, and the 21mm x 37mm mounting hole size against your existing switch and panel opening before buying.
