KEY SWITCH RK 28 E

The RK28-E is a momentary-action pushbutton switch designed for the instantaneous control of signal and control circuits in small household appliances and industrial equipment.

The RK28-E is a momentary (spring-return) pushbutton switch with a panel mounting size of 27 x 23 mm. The circuit state changes as long as the button is pressed; when the button is released, the spring mechanism returns the contact to its original position. With its NO-NC configuration, it is suitable for both normally open and normally closed circuit applications.

The product operates at 250 V and 2.5 A and is designed for use in low-current control circuits. Its 50,000-cycle lifespan indicates suitability for frequently repeated control operations, while the T55 class indicates it can operate at ambient temperatures up to 55 °C. Connection is made via a 4.8 x 0.50 mm tab terminal.

The RK28-E, with a lifespan of 50,000 cycles, delivers long-lasting and reliable performance in heavily controlled circuits.

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 indicates the switch’s mechanical and electrical resistance to repeated operation; the T55 class denotes its ability to operate at ambient temperatures up to 55 °C. When selecting a product, ensure that the 250 V / 2.5 A ratings are compatible with the circuit conditions.
