Hella Rocker Switch On/off Spst 10A 12V Part No. 4446

The HELLA Rocker Switch is an On-Off SPST switch with contacts rated at 10A at 12V, making it a practical choice where a simple single-pole, two-position switch is required. It is supplied as an each unit and carries part number 4446 for identification when matching against an existing switch or wiring setup.

This switch uses a 20mm mount diameter with a 6mm mount length, and it has 3 terminals. The switch is non-illuminated and has no lamp colour specification, so it suits applications where illumination is not needed and where the installer is looking for a straightforward rocker-style control.

As a HELLA automotive electrical accessory, it sits within the fuses, breakers, relays and switches group. The rated power is 10 amps at 12 volts, so the key buying checks are the mounting size, terminal count, and the intended circuit load rather than shape alone. A three-year warranty is listed for the product.

Application and Buying Notes

Before ordering, check the existing switch opening and confirm the panel accepts a 20mm mount diameter with a 6mm mount length. Those two measurements are the most useful physical checkpoints here because rocker switches can look similar while differing in panel size, retention style, and terminal layout.

The electrical rating matters just as much as the physical fit. This HELLA switch is rated to 10A at 12V, so it should only be used where that current and voltage suit the circuit design. For any replacement job, compare the number of terminals as well; this unit has 3 terminals and a single-pole, two-position On-Off-SPST action.

Because the switch is non-illuminated, it is best suited to applications where no indicator light is needed. If the original switch had an internal lamp or a specific illuminated function, that should be matched carefully before purchase. Part No. 4446 is the clearest reference point when verifying against an existing part, especially where the old switch is worn, missing, or hard to read.

When replacing a switch in an automotive circuit, the safest approach is to confirm the connector arrangement, mounting dimensions, and load requirements before installation. The listing does not provide vehicle-specific fitment, so the part number and the measured panel opening should be used as the main comparison points rather than assuming compatibility from appearance alone.

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 4446 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 (Contacts Rated 10A @ 12V). Part number 4446 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 4446, 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.

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 HELLA Part No. 4446, the 20mm mount diameter, 6mm mount length, 3 terminals, and the required 10A at 12V On-Off-SPST switching action before purchase.
