Snap action switches are highly sensitive switches that respond to very small movements and can rapidly change from one contact position to the other. This Roller Lever Switch is mostly used in timing devices, test instruments, vending machines, aerospace, medical and dental equipment, appliances, computer and business equipment, communications equipment and manually operated devices.

311SM4-T Snap Action Switch from Honeywell comes with a long operating life and an elongated mounting hole for easier, more accurate mounting. Featuring a choice of actuation, electrical termination and operating characteristics, this subminiature basic switch offers reliable functionality and is used for simple or precision application needs.

Product Highlights
  • Optional series constructions available (gold contacts for low energy switching, bifurcated gold contacts for maximum reliability, power load switching capability to 11 A)
  • Choice of electrical termination (solder, quick connect, PCB)
  • Long operating life
  • Elongated mounting hole for easier, more accurate mounting
  • Choice of actuation (plunger, as well as a variety of integral and auxiliary actuators)
  • 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)

Potential Applications:
  • Aerospace
  • Instrumentation
  • Appliances
  • Vending machines
  • Timing devices
  • Office equipment
  • Computer/business equipment
