NKK Switches Miniature PCB Process Sealed Rotary MRB14B-BA

The MRB14B-BA is a miniature, sealed, PCB-mounted rotary switch with SP3T circuitry and 45° indexing, featuring straight PC terminals with a bracket. It has a 6mm double-flat brass bushing, beryllium copper contacts with gold plating, and a polyamide base. Maximum resistive load is 0.4VA at 28V AC/DC, with contact resistance under 80 milliohms and insulation resistance over 100 megohms at 500V DC. Operating temperature ranges from -10°C to +70°C. IP67 sealing is achieved with the optional AT535 o-ring. Contact timing is nonshorting (break-before-make). Mechanical life is 30,000 operations, electrical life 10,000. Terminal spacing is 2.54mm × 2.54mm. Mounting torque is 0.686 Nm. The switch is not UL or CSA certified.
