Typical applications for the high-precision My-Com limit switches:

  • Reference point setting in X/Y tables and machine tools
  • Monitoring of the closing and locking accuracy of injection moulds
  • Detection of the tiniest deflections, movements and deformations
  • Integration in measuring sensors, gages and activating pins
  • Calibration of measuring instruments in quality control
  • Monitoring of surface roughness
  • Other applications in precision mechanical engineering


A strong focus in the My-Com design was limiting the number of components to the absolute minimum. Just three moving parts and high-quality materials guarantee an enormous number of switching operations with constant repeat accuracy. Short, linear travel in just two directions and sensitive to even the slightest  activating force further increase both reliability and service life of the My-Com precision switch, which has been proving absolute reliability in over 1 million applications.
