KEY SWITCH RK 28 A

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

The RK28-A is a momentary (spring-return) pushbutton switch designed for mounting in a 27 x 23 mm panel. The contact changes position during actuation and returns to its initial position via spring force when pressure is released. Thanks to its NO-NC configuration, both normally open and normally closed circuit configurations can be accommodated with the same product, providing flexibility in control and position sensing applications.

Rated at 2.5 A at 250 V, the RK28-A is designed for use in low-current control and signal circuits. With a T55 temperature class and a service life of 50,000 cycles, it is used in small household appliances and industrial equipment where frequent control operations occur. Connection is provided via a 4.8 x 0.50 mm tab terminal.

The RK28-A offers long-term, stable operation in frequently actuated applications, with a service life 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. The 50,000-cycle service life indicates the switch’s mechanical and electrical durability against repeated actuation; the T55 class indicates that it can operate at ambient temperatures up to 55 °C. The 250 V / 2.5 A ratings define the circuit conditions under which the product is intended for use, and these limits must be taken into account when making a selection.
