KEYBOARD RK 29 B

The RK29-B is a momentary-action pushbutton switch designed for the instantaneous control of low-current control circuits in small household appliances and industrial equipment.

The RK29-B is a momentary (spring-return) pushbutton switch designed for mounting in an 8.5 x 28 mm panel. The circuit state changes while the button is pressed; when the button is released, the spring mechanism returns the contact to its original position. The NO-NC configuration allows a single product to meet both normally open and normally closed circuit requirements.

With a current rating of 0.25 (0.1) A at 250 V, the RK29-B switches 0.25 A with resistive loads and 0.1 A with inductive loads. These values make the product suitable for use in signal and control circuits, while its 50,000-cycle lifespan demonstrates its suitability for frequently repeated control operations. Temperature class T55 indicates that it can operate in environments up to 55 °C; connections are provided via 4.8 x 0.80 mm or 2.8 x 0.50 mm tab terminal options.

The RK29-B offers long-term stability in frequently operated control circuits with a lifespan of 50,000 cycles.

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. A 50,000-cycle lifespan defines the switch’s mechanical and electrical resistance to repeated operation; the T55 class specifies that it can operate at ambient temperatures up to 55 °C. When selecting the product, ensure that the 250 V / 0.25(0.1) A ratings are compatible with the circuit conditions in the application.
