Products // Switches and Jacks // 28-17. Shorttravel pushbutton

  • ESD protection to front 15 kV
  • mechanical lifetime 250000 cycles
  • sealed against cleaning fluids

Integrated circuits are very ESD sensitive. Therefore this shorttravel pushbutton is designed with sufficient distance from front to solderpins of 15kV ESD protection. The specialy designed contact bridge of CrNi-steel guarantees electrical life with min. 250000 operations. The pushbutton is sealed against soldering fluids and watertight on request.
