KEY SWITCH RK 09

RK09 is a momentary-push-button switch developed for position sensing and instantaneous control in home appliances and industrial equipment.

The RK09 is a momentary (spring-return) pushbutton switch that is mounted via a Ø5 mm mounting hole and operates on the push-button principle. It changes position as long as the button is pressed and returns to its initial position when released, thanks to the spring. Its NO-NC configuration allows it to be used in both normally open and normally closed circuit applications, making the product flexible for applications requiring lid position detection and momentary control.

Offering current options of 16(4) A and 10(4) A at 250 V, the RK09 switches at 16 A or 10 A for resistive loads and 4 A for inductive loads. With a T125 temperature class and a 50,000-cycle lifespan, it is used in home appliances, small household appliances, and industrial equipment where frequent control operations occur. Connection is provided via a 6.3×0.80 mm or 4.8×0.80 mm tab terminal, depending on the application.

With a service life of 50,000 cycles and a glowing wire resistance of 850 °C, the RK09 ensures long-term, safe operation in frequently controlled applications.

The product is designed and tested in accordance with the requirements of the EN 61058-1 standard, which covers switches used in household and similar appliances. The 850/750 °C glowing wire (GWIT) values indicate the housing material’s resistance to ignition, while the T125 class specifies the ability to operate at ambient temperatures up to 125 °C, while the 50,000-cycle service life defines its mechanical and electrical endurance against repeated actuation. The IP00 rating indicates that the housing provides no protection; therefore, the RK09 is designed to be mounted inside an enclosure that provides the necessary protection.
