Application and Buying Notes

When comparing this switch to a replacement part, start with the part number 0340302111, then confirm the physical and electrical details. The important checks here are 12 or 24V compatibility, 7 terminals, 28mm mount diameter, 10mm mount length, and the hazard switch function with headlamp flasher.

The 10A contact rating at 12V is a practical detail, not a universal fitment promise. If the original switch has a different terminal count, different mounting size, or a different switching action, this Bosch unit may not suit without further checking.

Red illumination is part of the listed design, so it suits applications where an illuminated switch is required. If the vehicle or equipment uses a different lamp colour or a non-illuminated arrangement, that should be verified before ordering.

Because no model-specific fitment has been supplied, the safest approach is to compare the original switch, connector layout, and mounting dimensions against the listed details. That is the most reliable way to avoid ordering the wrong part.

The one-year warranty applies to the product as listed, but warranty cover does not replace the need to confirm fitment and electrical suitability. A switch can be the correct Bosch part and still be wrong for a particular vehicle if the mounting or terminal arrangement is different.

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 0340302111 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.
