NKK Switches Half-Inch Diameter Process Sealed Rotary MRA206-BE

The MRA206-BE is a half-inch diameter, process-sealed rotary switch with a shaft actuator and PCB terminals, rated for 250mA at 125V AC resistive load. It has 2 poles and 2 to 6 position settings with 30° indexing and nonshorting break-before-make contact timing. Contact resistance is ≤10 milliohms, insulation resistance ≥100 megohms at 500V DC, and dielectric strength is 1,000V AC for 1 minute. Mechanical life is 30,000 operations; electrical life is 10,000 operations. Operating torque is 0.02 to 0.07 Nm. The shaft is nickel-plated brass, contacts are silver-plated copper, and the base is diallyl phthalate. Operating temperature ranges from -10°C to +70°C. Mounting torque is 0.686 Nm. The switch includes a plain black knob and is designed for panel mounting with a 0.220-inch cutout and keyway.
