Precision mechanical switches My-Com®

Micrometer precision: 70 times more accurate than a hair is thick!

With a repeat accuracy of 1 micron, the My-Com® remains undisputedly the most accurate and most compact mechanical switch in the world. The standard My-Com® range of the most diverse mechanical and electric types largely reflects the requirements of the market. With its extremely compact design, the My-Com® can also be easily integrated in very constrained surroundings.

    Special features
    • Rigorous attention was paid to the design of the My-Com® precision switch to reduce the number of components to an absolute minimum. Just three moving parts and high-quality materials guarantee a large number of switching operations with constant repeat accuracy. Short, linear displacements in just two directions and low activating forces further increase the reliability and service life of the My-Com® precision switch. The My-Com® has proven its impressive reliability in over 1 million applications.

      0,001 mm repeat accuracy

      Ensured reliable repeat accuracy of one micrometer makes My-Com® the most precise limit switch in the world. The mechanical device – with a service life of 10 million switching operations – provides ultra-precise reference signals for most diverse applications.

      1 μm accuracy even in harsh environments

      My-Com® precision switches retain their ultimate precision even under most adverse conditions. Viton and silicone gaskets prevent the gold-plated contacts from impairment by dirt, dust and condensation and thus ensure constant micrometer switching precision throughout the entire service life.
