DESCRIPTION

A Snap Action Switch is a type of momentary contact micro switch which operates at a rapid speed as it takes very little force or stimulus to operate. Snap action switches are highly sensitive switches that respond to very small movements and can rapidly change from one contact position to the other. The SM series sub-miniature basic switches are used for simple on/off application needs and are therefore widely used in aerospace, instrumentation, timing devices, computer and business equipment, test instruments, HVAC equipment, manually operated devices, etc.

21SM284 Snap Action Switch from Honeywell features a long operating life and an elongated mounting hole which enables easier and accurate mounting. This Snap Action Switch offers a choice of actuation, electrical termination and operating characteristics for optimum functionality.

Product Highlights:

  • MIL-PRF-8805 qualified listings available
  • Long operating life
  • Choice of operating characteristics (sensitive differential travel as low as 0.0254 mm [0.001 in] maximum, low operating force to 0.56 N [2.0 oz.] maximum)
  • Optional series constructions available
  • Elongated mounting hole for easier, more accurate mounting
  • Choice of actuation (plunger, as well as a variety of integral and auxiliary actuators)
  • Choice of electrical termination (solder, quick connect, PCB)

Potential Applications:

  • Aerospace
  • Instrumentation
  • Appliances
  • Vending machines
  • Timing devices
  • Office equipment
  • Computer/business equipment
  • Test instruments
  • Medical/dental equipment
  • Communications equipment
  • HVAC equipment
  • Manually operated devices
  • Valves
