Hella Toggle Switch On/off/on Spdt 20A 12V Part No. 4302

The Hella Toggle Switch On/Off/On SPDT is a 3-position switch with 3 terminals, rated at 20A at 12V and 10A at 24V. It uses a 12mm mount diameter and suits a panel opening of 12mm, with a mount length of 5mm and suitability for panels up to 5mm thick.

This is a non-illuminated switch with no lamp colour specified, so it is aimed at straightforward control applications where the contact rating and physical fit are the main concerns. The part number is 4302, and the unit is supplied as each.

As a single-pole toggle switch, it provides an On-Off-On action with SPDT contacts. That makes it important to match the switch function, terminal count, and panel thickness to the application before ordering, especially where the existing installation already uses a 12mm opening.

Application and Buying Notes

Before buying, confirm that your panel has a 12mm opening and that the panel thickness does not exceed 5mm. The supplied mount diameter and mount length are the key physical checks for this switch, and they matter just as much as the electrical rating when replacing an existing toggle.

The switch is rated at 20A at 12V and 10A at 24V, so it needs to be matched to the circuit demand rather than used as a general replacement without checking load. If the original switch is also an On-Off-On SPDT unit with 3 terminals, that is the closest comparison point for installation.

Because this switch is non-illuminated, it will suit applications where a lighted switch is not required. If your current setup relies on an illuminated face or different terminal layout, the 3-terminal, single-pole configuration here should be checked carefully against the vehicle or equipment wiring before fitting.

For replacement work, part number 4302 is the most reliable reference along with the physical size and switch action. If you are matching an existing switch, compare the part number, the 12mm mounting size, the On-Off-On operation, and the number of terminals to avoid ordering the wrong control.

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 4302 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 Toggle Switch On/Off/On SPDT (Contacts Rated 20A @ 12V). Part number 4302 should be checked first. Listed voltage is 12. Listed output rating is 20. These details form the core reference points used by parts interpreters when confirming the correct replacement.

For part number 4302, 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 20 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 checking part number 4302, the 12mm mounting opening, the 3-terminal On-Off-On SPDT action, and the panel thickness limit of 5mm before purchase.
