Hella Rocker Switch On/off Spst 24V Red Illuminated 10A HM4400R

The HELLA HM4400R is a rocker switch with an On - Off - SPST action, rated at 10A on 24V systems. It is a red illuminated switch with 3 terminals, designed for installations where a simple two-position control and visible switch indication are required.

This switch has a 20mm mount diameter and a 2mm mount length, so the panel opening and available installation depth need to suit those dimensions. With 1 pole and 2 positions, it is a straightforward electrical control component rather than a multi-function switch.

The part is supplied as a single each unit and is listed under HELLA part number HM4400R. The one-year warranty provides a basic level of purchase confidence, but correct application still depends on matching the electrical rating, terminal count, and mounting size to the job at hand.

Application and Buying Notes

Before ordering, check that your panel accepts a 20mm mount diameter and that the available mounting depth suits the listed 2mm mount length. These are practical checks that matter as much as the electrical rating, especially when replacing an existing rocker switch in a tight dash or console panel.

The switch is rated at 10A on 24V systems, so it should be matched to the circuit’s voltage and current demand. A 3-terminal, 1-pole On - Off - SPST layout also means you should confirm the wiring arrangement before purchase, particularly if you are replacing a switch that has a different terminal count or switching function.

The red illumination may be useful where you want the switch to be easy to identify in low light, but illumination does not replace proper wiring checks. Confirm that the application is intended for a 24V illuminated rocker switch and that the part number HM4400R is the correct replacement for your setup.

If you are comparing alternatives, use the listed part number, mounting size, terminal count, and switch action together rather than relying on appearance alone. Two switches can look similar from the front while differing in voltage rating, terminal layout, or illumination style, which can affect installation and function.

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 HM4400R 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.

Hella Rocker Switch On/Off SPST 24V Red Illuminated (Contacts Rated 10A @ 24V). Part number HM4400R should be checked first. Listed voltage is 24. Listed output rating is 10. These details form the core reference points used by parts interpreters when confirming the correct replacement.

For part number HM4400R, 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 24 and output 10 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: Please confirm compatibility by checking part number HM4400R, 24V system voltage, 10A rating, 20mm mounting diameter, 3 terminals, and On - Off - SPST switch action against your existing switch or application details.
