KEY SWITCH RK 26 B

The RK26-B is a round-body momentary-action switch designed for internal current control in home appliances and small household appliances.

The RK26-B is a momentary (spring-return) push-button switch with mounting dimensions of Ø20 x Ø22.8 mm. The contact changes position as long as the button is pressed; when released, it returns to its initial position due to spring force. Its NO-NC configuration allows for both normally open and normally closed circuit configurations within the same product.

The RK26-B, which offers 250 V, 4 A, 10(4) A, and 16(4) A current options; in the 10(4) A and 16(4) A variants, it switches 10 A or 16 A for resistive loads and 4 A for inductive loads. With a T125 temperature class and a lifespan of 10,000 cycles, it is used in white goods, small household appliances, and industrial equipment. Its round body design fits into circular panel cutouts, while the 6.3 x 0.80 mm tab terminal connection enables quick installation.

The RK26-B, with a T125 temperature class and a glowing wire resistance of 850 °C, ensures safe control in devices that operate unattended.

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 850/750 °C glow-wire (GWIT) values define the housing material’s resistance to ignition; the T125 class indicates the ability to operate at ambient temperatures up to 125 °C; and the 10,000-cycle lifespan defines the long-term durability of the contacts. The IP40 protection rating indicates protection against solid objects; since there is no water protection, the product must be used in a dry environment.
