KEY SWITCH RK 41

The RK41 is a momentary-action pushbutton switch developed for instant control with visual feedback in home appliances and industrial equipment.

The RK41 is an illuminated pushbutton switch with a mounting diameter of Ø19.75 mm that is installed on a panel. It operates in momentary (spring-return) mode. The contact changes position only while the switch is actuated; when the button is released, it returns to its initial position due to spring force. The built-in illumination allows the user to see the actuation status or the device’s condition directly on the panel.

With a maximum current rating of 100 mA, the RK41 is designed for use in low-current control and indicator circuits rather than for power line switching. With a T70 temperature class and a lifespan of 10,000 cycles, it is used in user interfaces for white goods, small household appliances, and industrial equipment. Connectivity is provided via the RAST 2.5 socket system, which enables fast and error-free assembly using pre-wired cable harnesses on the assembly line.

With its RK41 rating, T70 temperature class, and 10,000-cycle lifespan, the RK41 ensures reliable operation in frequently used panel interfaces.

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 devices. The T70 class indicates that the switch can operate at ambient temperatures up to 70 °C; the 10,000-cycle service life rating indicates that the contacts meet the expected mechanical and electrical durability throughout their service life. The maximum current limit of 100 mA is a key criterion that must be evaluated in conjunction with the circuit’s load conditions when selecting the product.
