SPST-NO, SPST-NC Microswitch Snap Action Switches:

3,261 Products Found

Farnell provides microswitches, also known as snap-action switches, that are designed to operate in applications requiring fast and reliable switching with minimal actuation force. These switches feature a mechanism that instantly changes contacts when the actuator is triggered, providing a quick response.

Microswitches are widely used in safety circuits and applications where precision and speed are critical. Their high reliability and ability to handle both low and high currents make them ideal for demanding industrial, automotive, and consumer applications.

Applications:

  • Safety Systems: Door switches and safety interlocks in industrial machinery.
  • Appliances: Limit switches in washing machines, ovens, and dishwashers.
  • Automotive: Seatbelt and airbag activation systems.
