Hella Rocker Switch On/off Spst 24V Amber Illuminated 10A HM4400A

The Hella HM4400A is a rocker switch with an On - Off - SPST action, designed for 24V electrical systems and rated at 10A @ 24V. It is an illuminated switch with an amber lamp colour, which makes it suitable where a visible switched indication is needed in a 24V setup.

This switch has 3 terminals, 1 pole, and a 2-position layout. The mount diameter is 20mm, with a mount length listed at 2mm. Those dimensions matter when checking panel compatibility, as the switch needs to suit the opening and available space behind the mounting surface.

Brand identification is straightforward here: Hella, part number HM4400A. The unit is supplied each, weighs .013kg, and carries a one year warranty. For buyers replacing an existing switch or planning a new installation, matching the part number, voltage, terminal count, and mounting size is the safest place to start.

Application and Buying Notes

Before buying, confirm that your application uses a 24V circuit and that the load stays within the 10A contact rating at 24V. A switch can look similar from the front yet differ in terminal count, position type, or mounting size, so the 3-terminal layout and 20mm mount diameter should be checked against the panel and wiring you already have.

If you are replacing an existing switch, compare the part number HM4400A as well as the physical details: rocker style, illuminated operation, amber lamp colour, 1 pole, and 2 positions. These details help separate this switch from other Hella rocker switches that may look alike but use different electrical or mounting configurations.

Take care with the installation space behind the panel. The listed mount length is 2mm, and the switch weighs .013kg, so the size is compact, but the surrounding wiring and connector arrangement still need to suit the 3 terminals. A proper match is determined by the electrical rating, terminal layout, and panel opening together, not by appearance alone.

Warranty coverage is one year, so keep your purchase details and confirm the switch is suitable before fitting. If the original component is damaged, missing, or unreadable, the most reliable check is to compare the 24V rating, 10A contact rating, and part number HM4400A with the vehicle or equipment specification.

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 HM4400A 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 Amber Illuminated (Contacts Rated 10A @ 24V). Part number HM4400A 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 HM4400A, 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: Confirm compatibility by matching part number HM4400A, the 24V system requirement, 10A contact rating, 3 terminals, and 20mm mount diameter before purchase or installation.
