Hella Toggle Switch On/off/on Spdt 12V Green Illuminated 15A Part No. 4206

The Hella toggle switch, part number 4206, is an On/Off/On SPDT switch designed for 12V electrical systems. It has 4 terminals, 3 positions, and green illumination, with contacts rated at 15A @ 12V. That combination suits a range of low-voltage vehicle control applications where a compact panel-mounted switch is required.

Mounting is through a 19mm diameter opening, and it is specified for panels up to 2mm thick. The listed maximum load is 12V/6A, so the practical load requirement should be checked carefully against the circuit you intend to switch. The lamp bulb type to suit is 12V/292.

This is a single pole toggle switch with an On - Off - On action, which means the centre position is off and the two outer positions provide the switched outputs. If you are replacing an existing switch, the most important checks are the 19mm mounting hole, the 4-terminal layout, the 12V system voltage, and the part number 4206. Those details will do more to confirm suitability than the switch style alone.

Application and Buying Notes

Before ordering, compare the part number 4206 with the switch you are replacing, then check the panel opening carefully. This switch needs a 19mm diameter opening and is listed for panels up to 2mm thick, so both the hole size and panel thickness matter. The 4-terminal arrangement and On - Off - On SPDT operation should also match the original switch function if you are swapping like for like.

The electrical ratings need the same level of attention as the physical size. The contacts are rated 15A at 12V, while the listed maximum load is 12V/6A. That means the application should be checked against the lower specified load where relevant, rather than assuming the higher contact rating covers every use. For anything with a heavier current draw, confirm the circuit requirements before fitting.

The green illumination may be useful where the switch needs to be visible at night or in low light, but the bulb type is specific: 12V/292. If the illumination matters to your application, make sure the replacement lamp specification matches what you need. It is also worth confirming the terminal count and the switch action against the wiring layout before installation, especially where the original switch controls two switched positions with a centre off.

For a clean replacement job, confirm the existing switch aperture, terminal arrangement, and panel thickness before purchase. The dimensions and electrical figures are the most reliable guide here: 19mm mount diameter, 2mm mounting length, 4 terminals, 12V operation, and 15A contact rating. Matching those details helps reduce the risk of buying a switch that looks close but does not suit the vehicle or panel setup.

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 4206 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 12V Green Illuminated (Contacts Rated 15A @ 12V). Part number 4206 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 4206, 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 matching part number 4206, the 19mm mounting opening, the 4-terminal On - Off - On SPDT layout, and the 12V electrical requirements before ordering. If the original switch differs in terminal count, panel thickness allowance, illumination type, or load rating, it should be checked carefully against this listing.
