KEY SWITCH RK 04

The RK04 is a wide-button switch developed for internal current control in home appliances, heating and ventilation systems, and industrial equipment.

The RK04 is a pushbutton switch manufactured with a panel size of 22 x 30 mm. It is available with On-Off, illuminated On-Off, reversing, and momentary (spring-return) operating functions; thus, control requirements for permanent on/off, direction reversal, and return to the initial position when released are all met within the same housing size. The illuminated option allows the device’s operating status to be viewed directly on the panel.

Offering current ratings of 16(4) A and 10(4) A at 250 V, the RK04 switches at 16 A or 10 A for resistive loads and 4 A for inductive loads. With a T125 temperature class and a lifespan of 10,000 cycles, it is suitable for use in white goods, small household appliances, heating and ventilation systems, and industrial equipment. Connections are made using 6.3×0.80 mm or 4.8×0.80 mm tab terminals, depending on the application, enabling quick, solder-free connections on the assembly line.

With an 850 °C glow wire resistance rating and a T125 temperature class, the RK04 operates reliably in areas of the device that are continuously exposed to heat.

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 glow-wire (GWIT) values define the housing material’s resistance to ignition, while the T125 class specifies the ability to operate at ambient temperatures up to 125 °C. The IP20 protection rating provides protection against solid objects; since it does not include water protection, the product is suitable for installation in dry environments inside devices. The 10,000-cycle lifespan ensures consistent contact performance throughout the switch’s service life.
