KEY SWITCH RK 26 D

The RK26-D is a momentary-action pushbutton switch designed for instantaneous circuit control in home appliances, small household appliances, and industrial equipment.

The RK26-D is a momentary (spring-return) pushbutton switch mounted in a 16.5 x 20 mm panel opening and operating on the pushbutton principle. The contact changes position while the button is pressed; when the button is released, it returns to its initial position due to spring force. The NO-NC configuration allows the same product to meet both normally open and normally closed circuit requirements.

The RK26-D, which offers 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, heating and ventilation equipment, and industrial equipment. Connection is provided via a 6.3 x 0.80 mm tab terminal, enabling solderless wiring on the assembly line.

With its T125 temperature class and 850 °C glow-wire resistance, the RK26-D operates safely in areas of equipment exposed to heat.

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 ignition (GWIT) values define the housing material’s flammability behavior; the T125 class indicates operation 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.
