Cole Hersee Toggle Switch Spst Off/mom On 12/24V 25A Screw Terminals Part No. 55020BL

The Cole Hersee toggle switch in this listing is a single pole, single throw unit with an Off / Momentary On action, 2 screw terminals, and a 12/24V dual voltage rating. It is marked at 25A at 12V and 12A at 24V, which makes the current rating and operating voltage the key checks before ordering.

It uses a 12mm mount diameter with a stem thread of 15/32-32, a stem length of 12mm, and a stem diameter of 12mm. The panel thickness stated is 6.35mm, so the switch should be matched to the panel or mounting surface rather than assumed to suit every dash or console opening.

The switch is non illuminated and uses silver contacts. Overall dimensions are listed as H 28 x D 41 x W 16mm, and the handle length is 17mm. The part number is 55020BL and the unit is sold each, which is useful when comparing against existing hardware or a replacement requirement.

Application and Buying Notes

This switch should be selected on the basis of its electrical rating and physical dimensions, not by appearance alone. The important details here are SPST Off / Momentary On action, 2 screw terminals, 12/24V dual voltage, and the 25A at 12V and 12A at 24V ratings. If the circuit draw or operating voltage does not line up with those figures, it is not the right match.

Mounting is another point to check carefully. The listed mount diameter is 12mm, the stem thread is 15/32-32, and the stated panel thickness is 6.35mm. Those measurements need to suit the panel, bezel, or bracket you are fitting into, otherwise the switch may not seat or clamp correctly.

Because this is a non illuminated toggle switch, it is suited to applications where no lamp is required in the switch body. The silver contacts and screw terminals are practical details to confirm when you are replacing an existing switch with the same style of termination and contact arrangement.

If you are replacing a worn unit, compare the existing switch against the part number 55020BL, the Off / Mom On switching action, and the physical dimensions H 28 x D 41 x W 16mm. Matching those details reduces the chance of ordering a switch that looks similar but behaves differently in service.

When in doubt, use the application details already on the vehicle or equipment and compare them against the voltage, current, mounting, and terminal style shown here. That is especially important on control circuits where a momentary function is required, because a standard on/off toggle will not perform the same job.

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 55020BL 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 SPST Off/Momentary On Screw Terminals. Part number 55020BL 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 55020BL, 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 suitability by checking the part number 55020BL, the SPST Off / Momentary On action, the 12/24V rating, the 12mm mount diameter, and the 2 screw terminals against the existing switch and application before ordering.
