Crouzet Microswitch Range

65+ Years Designing & Manufacturing
Snap-Action Electrical Microswitches

Crouzet offers an extensive choice of standard or customized Classic, Miniature, Subminiature and Sub-subminiature micros-witches, with a large range of switching ratings from 1 mA to 25 A, magnetic blowout versions for High DC ratings, sealed models, positive break versions, a wide range of operating temperatures, special models for explosive atmospheres, long service life and an enormous variety of actuators, contact materials and fixing means.

Basic Technical Concepts

Our microswitches are high-precision, snap-action switches and these are the main features for which they are notable:

  • Fast and reliable switching largely independent of actuating speed
  • High electrical ratings but small dimensions
  • High repeat accuracy of switching points and forces
  • Low operating force
  • Short pre-travel but large overtravel
  • Very long service life
  • Extensive range of connections, fixing means and actuators for easy adaptation to numerous applications
