NKK Switches Half-Inch Diameter Process Sealed Rotary MRA112-CC

The MRA112 is a half-inch diameter process sealed rotary switch with a single pole and 2 to 12 positions, featuring a shaft actuator with PC terminals and a self-cleaning sliding contact. It has a contact resistance of 10 milliohms maximum, an insulation resistance of 100 megohms minimum at 500V DC, and a dielectric strength of 1,000V AC for one minute. The electrical capacity is 250mA at 125V AC, with a mechanical life of 30,000 operations and an electrical life of 10,000 operations. The indexing angle is 30 degrees, and the operating torque range is 0.02 to 0.07 Nm. The shaft is brass with nickel plating, movable contacts are copper with silver plating, and the base is diallyl phthalate. The operating temperature range is -10°C to +70°C. The switch is designed for low-voltage, low-current logic-level circuits and meets no UL or CSA certifications.
