  • Spherical actuator allows actuation force off center ± 30˚ with regard to vertical
  • Total travel 1.6 mm
  • Sealed against flux Typical Applications
  • Automotive
  • Cranes, off road, railway
  • Factory automation
  • Security systems How To Order Our easy build-a-switch concept allows you to mix and match options to create the switch you need. To order, select desired option from each category and place it in the appropriate box. Specification FUNCTION: Momentary action CONTACT ARRANGEMENT: 1 make contact = SPST, N.O.

SOLDERING: Protected against flux and is compatible with the following soldering processes:

  • Fluxing of PCB bottom side
  • Preheating at 85˚C
  • Wave soldering (Tin/Lead 40-60) 250˚C for 2 sec.
  • Cooling down to ambient temperature.
  • Eventual cleaning by brushing on soldered side. TMS Freon to be avoided.
