KEY SWITCH RK 51

The RK51 is a push-button switch developed for controlling circuits carrying high inductive loads in home appliances and industrial equipment.

The RK51 is a pushbutton switch with panel dimensions of 11 x 30.2 mm. It is available with On-Off, illuminated On-Off, and reverser operating functions; the On-Off options permanently turn the circuit on or off, while the reverser option allows the circuit’s direction to be changed with a single control action. The illuminated option allows the device’s operating status to be monitored from the panel.

Offering current ratings of 10(4) A and 16(6) A at 250 V, the RK51 switches 10 A or 16 A for resistive loads and 4 A or 6 A for inductive loads. The variant with an inductive capacity of up to 6 A makes the product ideal for circuits containing motors and coils. With a T125 temperature class and a lifespan of 50,000 or 10,000 cycles depending on the variant, it is used in white goods, small household appliances, heating and ventilation equipment, and industrial equipment. Connections are provided via 6.3×0.80 mm or 4.8×0.80 mm tab terminal options.

With a T125 temperature class and a service life of up to 50,000 cycles, the RK51 offers long-term stability in frequently controlled high-temperature areas.

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 T125 class indicates that the switch can operate at ambient temperatures up to 125 °C; the life rating of 50,000 or 10,000 cycles, depending on the variant, defines the mechanical and electrical endurance of the contacts against repeated operation. The current ratings of 10(4) A and 16(6) A define the product’s operating limits in circuits containing both resistive and inductive loads.
