Hella Rocker Switch On/off Spst 12V Green Illuminated 10A Part No. 4434

The Hella rocker switch is a 12V illuminated switch with an On-Off SPST action and contacts rated at 10A @ 12V. It is identified as Part No. 4434 and is supplied as a single switch, which makes it a straightforward choice where a compact, panel-mounted control is needed.

This unit uses a 12mm mount diameter and 6mm mount length, with 3 terminals and 2 positions. The lamp colour is green, and the switch illumination is built in, which is useful where the operator needs a clear visual reference in low-light conditions.

As a Hella auto electrical accessory, it sits in the switches category and is listed with a three-year warranty. The key details to confirm before ordering are the 12V operating voltage, 10A power rating, 12mm mounting size, and Part No. 4434.

The switch type is listed as rocker switch with a toggle-style action, and the product description specifies green illuminated contacts rated 10A at 12V. If you are replacing an existing switch, matching the part number, terminal count, and mounting dimensions is the safest way to avoid unnecessary returns.

Application and Buying Notes

Check the mounting hole size first, as this switch requires a 12mm mount diameter with a 6mm mount length. If the panel opening, bezel space, or mounting depth does not suit those dimensions, the switch may not install correctly even if the electrical rating is suitable.

Confirm the electrical match before buying. This unit is specified for 12V systems and has a 10A contact rating at 12V, so it should only be considered where those figures suit the circuit you are working on. Using the correct voltage and current rating is important for safe operation and service life.

The switch has 3 terminals, 1 pole, and 2 positions. That makes the terminal layout and action important when comparing it to a replacement switch, especially if the existing wiring relies on a specific terminal arrangement or switching function.

Green illumination can help the switch stand out on a panel, but it is still worth confirming the illumination style suits the application. If you are replacing an existing illuminated switch, compare the part number 4434, the terminal count, the 12mm mounting size, and the 12V specification before ordering.

The three-year warranty provides a clear service period, but it does not replace the need to verify fitment. A correct parts match should always be based on the part number and the application details for the vehicle or accessory installation.

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 4434 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 12V Green Illuminated (Contacts Rated 10A @ 12V). Part number 4434 should be checked first. Listed voltage is 12. Listed output rating is 10. These details form the core reference points used by parts interpreters when confirming the correct replacement.

For part number 4434, 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 10 should be checked carefully. Incorrect selection can affect installation time, return freight, and equipment availability.

Compatibility note: Confirm fitment by matching Part No. 4434, the 12V electrical rating, the 10A contact rating, and the 12mm mounting size against your existing switch or installation requirements before purchase.
