KEY SWITCH RK 15

The RK15 is a snap-action pushbutton switch designed for the instantaneous control of high-current circuits in home appliances and industrial equipment.

The RK15 is a momentary (spring-return) pushbutton switch secured with a Ø5 mm mounting hole. The snap-action mechanism ensures that the contacts switch instantly and precisely, regardless of the pressure applied to the button; this shortens the arc duration even when the button is pressed slowly and limits contact wear. When the button is released, it returns to its initial position due to spring force.

Available in current ratings of 10(4) A, 16 A, 18 A, and 25 A at 250 V, the RK15 operates at 10 A for resistive loads and 4 A for inductive loads in the 10(4) A variant. Depending on the variant, it features a T125 or T85 temperature class and a 50,000-cycle lifespan, making it suitable for use in home appliances, heating and ventilation equipment, and industrial machinery. Connections are made via a 6.3 x 0.80 mm tab terminal.

With a lifespan of 50,000 cycles and a resistance wire temperature rating of 850 °C, the RK15 provides a safety level suitable for repeated operation with loads of up to 25 A.

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 and T85 temperature classes specify the ability to operate at ambient temperatures up to 125 °C or 85 °C, depending on the variant, while the 50,000-cycle life rating defines its resistance to repeated actuation. The IP00 rating indicates that the housing provides no protection; therefore, the RK15 is designed to be mounted inside an enclosure that provides the necessary protection.
