VDO Push Button Switch Off - Mom On - Spst 10A 12V Part No. KN10-35

The VDO Push Button Switch is a simple 2-terminal, single-pole switch with an Off - Mom On - SPST action, rated at 10A and 12V. It is supplied as each and uses a 13mm mount diameter, which is the main physical size to confirm before ordering.

This switch is non-illuminated and has no lamp colour specified, so it suits applications where a plain push button function is required rather than a lighted control. The listed part number is KN10-35, and the brand is VDO.

With one position returning momentarily and the other remaining off, this style of switch is commonly selected where a brief circuit activation is needed. The contact rating of 10A at 12V should be checked against the load you intend to control so the switch is used within its stated limits.

Application and Buying Notes

Before buying, confirm the 13mm mount diameter matches the panel or bracket opening you have available. This switch is a push type with 2 terminals, so the wiring arrangement should also be checked against the circuit you are working on before installation.

The Off - Mom On - SPST action means the switch is intended for momentary operation rather than a maintained on/off function. That matters when matching the switch to the application, because a momentary contact is not the same as a latching switch with a fixed on position.

The listed electrical rating is 10A at 12V, so the connected load should stay within that rating. If the circuit draws more than 10 amps, or the system voltage differs from the stated 12V, this switch may not be suitable for the job.

Because the switch is non-illuminated and has no lamp colour, it is best suited to installations where backlighting or a visible status light is not required. If the original control was illuminated, that should be verified before ordering so you are comparing like for like.

Part No. KN10-35 is the strongest identifier for confirming you have the correct item. When comparing to an existing switch, check the part number, terminal count, action, and mount size together rather than relying on 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 KN10-35 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.

VDO Push Button Switch Off - Mom On - SPST (Contacts Rated 10A @ 12V). Part number KN10-35 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 KN10-35, 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.

Compatibility note: Confirm fitment by matching the part number KN10-35, the 13mm mount diameter, the 2-terminal layout, and the Off - Mom On - SPST switch action against your existing application before purchase.
