About Leman Avionics

Leman Avionics SA, based in Meyrin near Geneva, is a Swiss manufacturer of precision metal components with over 40 years of experience in the aerospace industry. The company was formed in 1992 through the spin-off of Sarcem Avionics from the Sarcem Group and later took over the firm MPW, founded in 1965, which is continued as the MecaProtoSwiss division. It manufactures micro-precise CNC components in small to medium series from metals and composite materials, including prototypes, toolmaking and cleanroom assembly of subassemblies. A key focus is mechanical altimetric and barometric counters in 2" or 3" standard sizes as well as custom sizes with calibration in IN-HG or millibar. Development is carried out with CAD/CAM support and microscopic quality control. In addition to aerospace, the company serves the medical technology, watchmaking and research sectors.
