KEY SWITCH RK 37

The RK37 is an on-off switch developed for in-unit current control in small household appliances and industrial equipment.

The RK37 is a pushbutton switch designed with an on-off operating function. Thanks to its latching mechanism, it remains in the position it is set to; the circuit maintains its open or closed state until the user intervenes again. This operating mode is suitable for basic on-off applications where the device’s operating state must be maintained continuously.

Rated at 6(2) A at 250 V, the RK37 switches up to 6 A for resistive loads and 2 A for inductive loads. With a T100 temperature class and a lifespan of 10,000 cycles, it is used in small household appliances, heating and ventilation equipment, and industrial machinery. Connection is provided via a 4.8 x 0.80 mm tab terminal, enabling solderless wiring on the assembly line.

RK37, with a wire resistance of 850 °C and a T100 temperature class, operates safely at in-device mounting points 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 (GWIT) values define the housing material’s resistance to ignition; the T100 class indicates operation at ambient temperatures up to 100 °C; and the 10,000-cycle lifespan defines the long-term durability of the contacts. The IP00 rating indicates that the housing provides no protection; therefore, the RK37 is designed to be mounted inside an equipment enclosure that provides the necessary protection.
