NSF Rotary Switch Shaft Assembly MU457848FPA(MA) for MU-MA Series, 12 Positions, 30° Throw, Shaft Length 0.41mm

NSF MU457848FPA(MA) Rotary Switch Shaft Assembly is a precision-engineered miniature shaft assembly designed exclusively for the MU-MA Series. This assembly features a double-spring detent mechanism, offering exceptional reliability and a life expectancy of over 100000 detent operations. With its compact structure and robust materials, this switch shaft assembly ensures precise rotary indexing and consistent switch performance across industrial, automation, and electrical control applications.

Designed for compact rotary switch systems, the shaft assembly provides a total of 12 switch positions with a 30° angle of throw, enabling versatile circuit configuration and control. The shaft length of 0.41mm and a shaft diameter of 6mm, along with M10 x 0.75 mounting bushes, ensure compatibility with miniature switch designs and reliable installation in limited-space environments. Adjustable end stops allow for customizable indexing ranges, making this assembly suitable for both standard and specialized switch panels.

The assembly is engineered to accommodate up to 8 miniature wafers, facilitating expanded switching configurations. Components feature glass-fibre loaded diallyl phthalate stators, polycarbonate rotors, and silver-plated contacts for superior electrical conductivity and mechanical durability. The overall length of 94mm, with a 12mm front shaft section, supports ergonomic integration into panel mount assemblies.

RoHS compliance ensures that the shaft assembly is safe for regulated industrial and laboratory use, meeting environmental directives for hazardous substance restrictions. Available in both break-before-make (BBM) and make-before-break (MBB) versions, the assembly allows for precise selection depending on the application requirements.

This robust shaft assembly is ideal for switch control installations within automation equipment, laboratory instrumentation, manufacturing controls, and commercial electrical systems.

NSF continues to bring high-quality rotary switch accessories to the market, making this MU457848FPA(MA) shaft assembly a trusted choice for engineers, technicians, and circuit designers.
