NKK Switches Half-Inch Diameter Process Sealed Rotary MRAN403-BG

The MRAN403-BG is a half-inch diameter, process-sealed rotary switch with four poles and 2-3 position settings, featuring PC terminals and a plain black knob. It operates with nonshorting, break-before-make timing using a self-cleaning sliding contact. Contact resistance is 10 milliohms maximum, insulation resistance is 100 megohms minimum at 500V DC, and dielectric strength is 1,000V AC for one minute. It is rated for 250 mA at 125 V AC resistive load, with a mechanical life of 30,000 operations and an electrical life of 10,000 operations. Operating torque is 0.02 to 0.07 Nm, indexing is 30 degrees, and the temperature range is -10°C to +70°C. The shaft is nickel-plated brass, contacts are silver-plated copper, and the base is diallyl phthalate. Mounting torque is 0.686 Nm. Maximum panel thickness for nonsealed mounting is 0.098 inch. It lacks UL or CSA certification.
