KEY SWITCH RK 08

RK08 is a push-button switch designed for panel-mounted control in heating and ventilation units, home appliances, and industrial equipment.

The RK08 is a push-button switch with a panel size of 29 x 36 mm. It offers two operating function options: On-Off and changeover; the On-Off option permanently turns the circuit on or off, while the changeover option allows the circuit’s direction to be changed with a control movement. Since both options can be implemented with the same panel cutout, a single mounting size can be used for models requiring different functions.

The product operates at 250 V; the 16(4) A and 10(4) A current options correspond to a switching capacity of 16 A or 10 A for resistive loads and 4 A for inductive loads. With a T125 temperature class and a 10,000-cycle lifespan, it is used in heating and ventilation systems, white goods, small household appliances, and industrial equipment. Terminal options for connection include 6.3 x 0.80 mm or 4.8 x 0.80 mm flat terminals.

With a wire resistance of 850 °C and a T125 temperature class, RK08 ensures safe operation in panel areas 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’s resistance to ignition; 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 IP20 protection rating indicates protection against solid objects; since there is no protection against water, the product is suitable for installation inside dry environments.
