Cole Hersee Toggle Switch Spdt On/off/on 12V 25A Blade Terminals Part No. 55016BL

The Cole Hersee 55016BL is a toggle switch with SPDT On / Off / On action, designed for 12/24V dual-voltage use and rated to 25A at 12V or 12A at 24V. It is a non-illuminated switch with 3 blade terminals and silver contacts, making it a practical choice where a compact, straightforward changeover switch is required.

Mounting is through a 12mm diameter hole, with a 15/32-32 thread stem measuring 12mm long and a 6.35mm panel thickness allowance. The handle measures 17mm, and the overall size is listed at H 29 x D 60 x W 16mm, so checking available clearance before purchase is worthwhile.

This switch is sold as a single unit and is backed by a one year warranty. The part number is 55016BL, and the listed brand is Cole Hersee, so matching the part number and terminal arrangement is the best way to confirm you are ordering the correct switch for the job.

Application and Buying Notes

The most important checks on this Cole Hersee 55016BL switch are the part number, the SPDT On / Off / On action, and the physical mounting dimensions. A 12mm mount hole is required, along with allowance for the 15/32-32 thread stem and the stated 6.35mm panel thickness, so it is sensible to confirm the panel setup before ordering.

Electrical suitability depends on the circuit load and voltage. The switch is rated at 25A at 12V and 12A at 24V, so it should be matched to the current demand of the application rather than assumed to suit every accessory circuit. The dual-voltage rating makes it useful where either 12V or 24V systems are involved, but the load still needs to be within the stated limits.

Terminal count and terminal style also matter. This unit has 3 blade terminals, and the listing also notes 2 terminals in the specifications, so it is best to verify the wiring layout against the intended application and the physical switch you are replacing. Matching the existing terminal arrangement is important where the circuit uses changeover switching.

Clearance is another practical check. The switch body is listed at H 29 x D 60 x W 16mm, with a 17mm handle, so make sure there is enough space behind and around the panel for the switch body, wiring, and any connector ends. This is particularly important in tight dash or console installations.

The switch is non-illuminated, so it will not provide built-in lighting or a status indicator. If your application needs an illuminated toggle or a separate lamp circuit, this model should only be chosen when a plain, unlit SPDT switch is what the installation calls for.

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 55016BL 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 Toggle Switch SPDT On/Off/On Blade Terminals. Part number 55016BL 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 55016BL, 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: Always confirm compatibility by matching the part number 55016BL, the SPDT On / Off / On action, the 12mm mounting requirement, and the 3 blade terminal layout against the existing switch and wiring in your vehicle or equipment.
