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

The MRAN403-A is a half-inch diameter, process-sealed rotary switch with four poles and two to three positions, using a shaft actuator with PCB terminals and a plain black knob. It has a contact resistance of 10 milliohms maximum and dielectric strength of 1,000V AC for one minute. Operating torque ranges from 0.02 to 0.07 Nm, with nonshorting (break-before-make) contact timing and 30° indexing. Mechanical life is 30,000 operations; electrical life is 10,000 operations at 250mA, 125V AC. The shaft is brass with nickel plating, contacts are copper with silver plating, and the base is diallyl phthalate. It operates from -10°C to +70°C and requires a mounting torque of 0.686 Nm. Not UL or CSA certified.
