KEY SWITCH RK 38

The RK38 is a momentary-action pushbutton switch designed for instantaneous control and position detection in home appliances and industrial equipment.

The RK38 is a momentary (spring-return) pushbutton switch secured with a Ø4.9 mm mounting hole. The contact changes position only while the switch is pressed; when the pressure is released, it returns to its initial position due to spring force. It is available with both NO-NC and NC-NO contact options, allowing the same product family to be used in circuits requiring either a normally open or normally closed initial state.

Offering current ratings of 6(4) A and 16(4) A at 250 V, the RK38 switches 6 A or 16 A for resistive loads and 4 A for inductive loads. With a T125 temperature class and a service life of 50,000 or 10,000 cycles depending on the variant, it is used in white goods, small household appliances, and industrial equipment. Connections are made via tab terminals measuring 6.3 x 0.80 mm or 4.8 x 0.80 mm, depending on the application.

With its RK38 and T125 temperature classes and a service life of up to 50,000 cycles, the RK38 ensures reliable operation in frequently controlled high-temperature environments.

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 T125 class indicates that the switch can operate at ambient temperatures up to 125 °C; the service life rating of 50,000 or 10,000 cycles, depending on the variant, defines the mechanical and electrical endurance of the contacts against repeated operation. The current ratings of 6(4) A and 16(4) A define the operating limits in circuits containing both resistive and inductive loads.
