Product Description

Elma MR50 is a precision 12-position SPST rotary selector switch engineered for reliable operation in demanding industrial and electronic applications. Featuring a robust die cast zinc housing, this compact switch measures 12.7mm in diameter and height, making it suitable for space-constrained PCB panel installations.

Rated to switch currents up to 200mA and maximum DC voltage of 28V, the MR50 switch provides effective single-pole single-throw (SPST) contact configuration with on-on switch positions, allowing for 12 unique selections. The switch offers mechanical longevity of 20,000 cycles and operates reliably in temperatures from -45°C to 85°C.

Its mounting is designed for panel integration, with IP68 front panel sealing providing industrial-grade environmental protection against dust and water exposure, making it ideal for outdoor and rugged conditions. The silver actuator and gold-plated contacts ensure efficient and low-resistance switching. The switch also complies with UL, RoHS, and ELV standards.

Typical applications include use in communication equipment, outdoor mobile devices, motorsport systems, aviation, military systems, and precision testing equipment. The combination of compact form factor, robustness, and environmental sealing makes the MR50 suitable for industrial, laboratory, and commercial electronics where reliable position switching is critical.
