Precision mechanical switches functionality

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.

Housing fronts and product variants

My-Com® high-precision switches excel by ultra-compact design merged with big product variety.
