Hella Toggle Switch On/off/on Spdt 15A 12V Part No. 4202

The Hella Toggle Switch On/Off/On SPDT, part no. 4202, is a 3-position switch rated at 15A at 12V and 7.5A at 24V. It uses push-on terminals and has 3 terminals, making it a straightforward choice where a compact toggle arrangement is required in an auto electrical setup.

This switch is non-illuminated and has an On - Off - On - SPDT action, so the centre position is off and the outer positions provide the two switched states. The mount diameter is 13mm, with a mount length of 6mm, and it is suitable for panels up to 6mm thick.

As a Hella electrical component sold individually, it sits in the fuses, breakers, relays and switches group and carries a three-year warranty. The listed description is Hella Toggle Switch On/Off/On SPDT with contacts rated 15A at 12V, which is the key detail to check before matching it to your circuit load.

Application and Buying Notes

Before buying, confirm the switch style and mounting dimensions against your panel and wiring setup. The important checks here are the 13mm diameter opening, the 6mm mount length, and the note that it suits panels up to 6mm thick. If your panel is thinner or thicker than that range, the switch may not seat or clamp as intended.

Electrical load also matters. The contacts are rated at 15A at 12V and 7.5A at 24V, so the current draw of the circuit needs to stay within those limits. If the application is close to the rated load, it is sensible to allow margin rather than treating the rating as a target.

The switch is a 3-terminal, single-pole, On - Off - On - SPDT unit with push-on terminals. That means the wiring layout needs to suit a three-terminal toggle arrangement, and terminal style should match the connectors already used in the vehicle or accessory circuit. If your existing switch uses a different terminal type or configuration, it is worth checking that before ordering.

Because this is non-illuminated and lamp colour is not applicable, it is best suited to applications where you do not need an internal indicator light. The practical value is in the basic switching function and the compact 13mm mount size, rather than added lighting or extra switch features.

If you are replacing an existing part, the safest comparison is the part number 4202 along with the published switch action and electrical ratings. Matching the part number, mounting opening, terminal count and current rating will reduce the risk of ordering the wrong component for the job.

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 4202 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.

Additional published details for cross-checking include Part No. 4202, Brand HELLA, Description Hella Toggle Switch On/Off/On SPDT (Contacts Rated 15A @ 12V), Number of Terminals 3, Switch Action On - Off - On - SPDT, Lamp Colour/s Not Applicable, Mount Length 6mm, Number of Positions 3, Switch Illumination Non Illuminated, Product Group 1 AUTO ELEC ACCESSORIES.

Hella Toggle Switch On/Off/On SPDT (Contacts Rated 15A @ 12V). Part number 4202 should be checked first. Listed voltage is 12. Listed output rating is 15. These details form the core reference points used by parts interpreters when confirming the correct replacement.

For part number 4202, 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 15 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.

In the absence of a verified fitment list, the safest approach is to compare the removed unit directly with the listed product details. That includes checking the housing style, pulley layout, regulator arrangement, and any visible identification numbers before supply is approved.

Compatibility note: Confirm compatibility by checking the part number 4202, the 13mm mounting opening, the 3-terminal On - Off - On - SPDT layout, and the 15A at 12V / 7.5A at 24V rating against your application before purchase.
